Right off the bat, the detection distances from this radar detector were the best of the bunch; its 2.1-mile rear detection is a half-mile farther than the Uniden R8's. Impressive stuff.
R8 Radar/Laser Detector. The R8 is Uniden's top-of-the-line offering. It can identify threats coming from all four directions thanks to its dual antenna, and you get notified via voice alerts.
DFR7. This low-cost detector has impressive range and all the requisite features, including GPS for low-speed false-alert muting, manual marking of up to 100 known radar locations, and speed ...
An early radar detector Car radar detector (Japanese) A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding.
It reports these detections (known as "plots") in polar coordinates representing the range and bearing of the target. In addition, noise in the radar receiver will occasionally exceed the detection threshold of the radar's Constant false alarm rate detector and be incorrectly reported as targets (known as false alarms). The role of the radar ...
where hr(km) is the height of the radar in km, and ht(km) is the height of the target in kilometres, and assuming standard atmospheric radio refraction. Thus, for a Kolchuga at 100 m altitude (above local terrain) and a target at 10 km (30 kft), the range of the system would be approximately 450 km.
