Test Data

Noted Abnormalities;

• patrol speed shadowing
  Radar traveling at 50 mph, shadowing from passing large trucks caused radar readings (mph) of:

This effect did not occur every time a truck passed. Radar measured patrol speed decreased momentarily several times when a passenger sedan passed patrol car.

• AC/Heater fan
  Antenna pointed at dash picked up readings from fan. Antenna aimed forward (not dash mounted) picked up fan easily.
• internal 100 watt mobile police radio
  Blanked out patrol and target speed readings.
• internal 2 watt handheld police radio
  No effect on strong target signals; on several weak signals radar displays dimmed and indicated random erroneous readings.

RANGE TEST DATA
Range test conducted on straight stretch of open 2 lane highway 1.8 miles long unless otherwise noted. (3) indicates test conducted on secondary road paralleled by high tension power lines mounted from metal poles. Radar operated from standard 4 door sedan.
