What are two factors that affect the performance of a radar?
Factors affecting radar performance. Transmitter power and antenna size The maximum range of a radar system depends in large part on the average power of its transmitter and the physical size of its antenna. (In technical terms, this is called the power-aperture product.) There are practical limits to each.
How much does a change in radar cross section affect a radar?
It would not be unusual for a slight change in aspect to cause the radar cross section to change by a factor of 10 to 1,000.
Is there a problem with the Nissan front radar?
But a problem with some of those radar modules — a third-party component supplied by Bosch — makes the sensor frequently deactivate itself, disabling cruise control and the emergency braking system. A warning flashes on the dashboard to indicate the problem: “Front radar unavailable due to obstruction.”
What does the radar do on a car?
One of those, automatic emergency braking (AEB), relies on a radar in the front grille to monitor a car’s proximity to the vehicle ahead, warn of possible collisions, and hit the brakes if the driver can’t.
When does front radar obstructed warning come on?
“FEB: Front Radar Obstructed” warning appears on panel between tach and speedo. The “collision warning system inactive” icon light comes on. After a few minutes, the warning message goes off; the collision warning system light goes off. Happens again after maybe ten minutes. Never seems to happen on slower, country road driving. Any ideas? Thanks.

Can a police radar be used in inclement weather?
The short answer is yes, it’s very accurate. Sometimes radar’s performance can be reduced during times of inclement weather, but that doesn’t reduce accuracy, just effective targeting ranges.
