Summary
The article discusses various aspects of radar technology and its applications. The key points covered include:
1. Radar detection range can vary from as low as 100 feet to over a mile. Sometimes, radar may track a distant large vehicle instead of a closer small vehicle without indicating which one it is tracking.
2. The US radar has a range of more than 250 miles and can be used for surveillance from the Earth’s surface to the stratosphere.
3. The range of radar depends on its specifications, with a maximum range of 128km. The minimum range is defined by the pulse width and can be as short as the time it takes for the radar pulse to travel one mile.
4. Radar detectors can detect radar signals but not police vehicles themselves. Most police cars do not carry radar, or officers turn it off during stops or when using it in instant-on mode.
5. Under ideal conditions, most police radars are accurate to about ±1 mph in measuring vehicle speed.
6. Lower altitudes and higher airspeeds can be used by aircraft to avoid radar detection by ground missile radars and surface-to-air missiles.
7. DeTect has developed the HARRIER BAR300, the largest and longest-range surveillance radar with an extended range of over 30 nautical miles for aircraft detection.
8. Radar systems are not able to detect stationary objects but only moving ones. They cannot accurately determine the source of the detected object.

How far can the US radar see
It contains a radar subsystem that permits surveillance from the Earth's surface up into the stratosphere, over land or water. The radar has a range of more than 250 miles (375.5 kilometers).
What is the range of a radar
The maximum range of the Radar for given specifications is 128km. The minimum range is defined by the pulse width. The time for the radar pulse to travel from the radar to a target 1 mile. Radar range is increased by the peak power.
Does radar detect all cops
A. Radar detectors can detect radar but not police vehicles. There's a good chance the police car wasn't radar-equipped (90 percent carry no radar). Or if it was, most officers shut off the radar while they're out of the car on a traffic stop or when using it in instant-on mode.
How accurate is police radar
Under ideal conditions most police radars are accurate to about ±1 mph. Microwave moving mode radar also measures patrol vehicle speed to an accuracy of about ±1 mph.
How low to avoid radar
In combat, many aircraft will operate at altitudes as low as 100 feet and at high airspeeds to defeat ground missile radars and avoid sophisticated surface-to-air missiles, anti-aircraft artillery, and enemy fighters.
What is the longest range radar in the world
DeTect's Largest, Longest Range Surveillance Radar: Aircraft Detection for 30 Nautical Miles. Leading radar manufacturer DeTect, Inc. has announced the production of the HARRIER BAR300, the company's largest and longest-range radar, featuring an extended range of more than 30 nautical miles for aircraft detection.
What can radar not detect
It's widely known that RADAR systems are not able to detect stationary objects, only moving ones. Actually, they are are to detect them but just not where they come from, so a barrier in the middle of the road and a traffic sign on the side of the street, they would look like the same to the RADAR system.
How accurate is radar range
Practically, the accuracy depends on the size of the individual range-cells in signal processing. ICAO recommends[3] a range cell size of 1/128 NM, i.e. about 14.5 m, for air traffic control air surveillance radar, which corresponds to a time interval of almost 10 nanoseconds.
Why doesn’t my radar detector go off when I pass a cop
A radar detector is not a police car detector. It's a radar detector. If a police officer doesn't have a radar gun in their vehicle (and many don't) or if they simply aren't actually running radar and transmitting, there's nothing for your radar detector to detect and thus it will stay silent. This is very common.
How accurate are police radars
Under ideal conditions most police radars are accurate to about ±1 mph. Microwave moving mode radar also measures patrol vehicle speed to an accuracy of about ±1 mph. Moving mode target vehicle accuracy is ±2 mph. Some microwave and laser radars specify accuracy based on a percentage of vehicle speed.
Can police radar see through walls
Police use radars to see inside homes. At least 50 US law enforcement agencies. Are now equipped with a radar device that allows them to detect human movement through the walls of houses.
What can radar not penetrate
Radio waves do not penetrate far through soils, rocks and most man-made materials such as concrete. The loss of radio reception or cell phone connection while driving a car through a tunnel or into an underground parking garage attests to this.
What can block radar

What is the most powerful radar in the US
The AN/FPS-85 radar operates at a frequency of 442 MHz (a wavelength of 68 cm) in the UHF band, just below the UHF television broadcast band, with a 10 MHz bandwidth and a peak output power of 32 megawatts.
How far does airport radar reach
60 nautical miles
The primary surveillance radar uses a continually rotating antenna mounted on a tower to transmit electromagnetic waves that reflect, or backscatter, from the surface of aircraft up to 60 nautical miles from the radar.
Can radar go through walls
It works in a range of around 50 feet. Though it "will penetrate most common building wall, ceiling or floor types — including poured concrete, concrete block, brick, wood, stucco glass, adobe, dirt" — the Radar-R does not work through metal.
How does police radar know which car is speeding
Police radar transmits radio waves at a fixed frequency. Some of the beam reflects from a target vehicle and returns to the radar. If the target is moving, a slight change in frequency occurs (Doppler shift). The radar does the heavy math and calculates target speed.
Can cops avoid radar detectors
Radar detectors can detect radar but not police vehicles. There's a good chance the police car wasn't radar-equipped (90 percent carry no radar). Or if it was, most officers shut off the radar while they're out of the car on a traffic stop or when using it in instant-on mode.
How do I not get detected by radar
How does it stay undetected first of all the plane is painted with a special coating. This special coating is called ramp or radar absorbent material this special paint contains lots of tiny metal
What is the weakness of radar
The radar sensor has a limited field of vision. In some situations, it may detect a vehicle later than expected or not at all. The radar sensor's detection of vehicles very close to your vehicle may be delayed in certain situations, e.g. if a vehicle pulls in between your vehicle and the vehicle directly ahead.
What is invisible to radar
While no aircraft is totally invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft avoiding detection by enemy radar and/or avoiding being successfully targeted by radar guided weapons.
What is the highest range of radar
The two types of radar use either the sky wave or surface wave and typical ranges are 100–3500 km and up to 500 km, respectively.
Which radar is better for long range
S-band radar is better for special applications and long-range detection. It is used more for surveillance as it provides better coverage.
Do planes lose radar over the ocean
Air traffic controllers typically track airplanes using radar technology, which is only effective for up to 200 miles offshore. After flying farther than 200 miles over the ocean, commercial airplanes are typically out of radar range.
