Stationary Radar The transition source stands still and the object receiving the energy moves. Moving Radar Both the patrol vehicle and the object being tracked are moving. Low doppler: reflects of roadway to detect patrol speed. High doppler: oncoming objects (target vehicle) Cosine Effect When a target vehicle's direction of travel creates a significant angle with the position of he stationary RADAR, the relative speed will be less than the true speed. Since the change in the signal's frequency is based on the relative speed, the RADAR speed measurement may be less than the car's true speed. This effect always works to the motorist's advantage when the RADAR is stationary. Three components of RADAR Antenna, box, current State v. Hanson Wisconsin Court addressed the use of moving RADAR. In addition to establishing that the unit was tested for accuracy, and the operator was properly trained in its use, the operator must establish the RADAR was used in an area where road conditions would distort readings as little as possible, and the PATROL VEHICLE'S SPEED WAS VERIFIED. Statutory speed laws Posted limits (Ex: 15 mph in school zones) Basic speed law any speed under the absolute limit that is safe for existing road, weather, or traffic conditions RADAR principle Doppler effect -Radio and light waves -Wavelengths
