Radar Operator EXAM COMPLETE QUESTIONS WITH 100% RATED CORRECT ANSWERS GRADED A+ 2025

Radar stands for - Correct Ans-Radio detection and ranging Radar is based on the - Correct Ans-Doppler effect Doppler detects - Correct Ans-Speed not direction or distance Radio waves are measured from the beginning of the - Correct Ans-Wave peak to the end of the wave valley All electric and radio waves have three things in common - Correct Ans-Wavelength frequency and speed The speed of light is - Correct Ans-186, 00 0 mi./s What equals the speed of light - Correct Ans-Radio wavelength multiplied by frequency Radar measures the - Correct Ans-Doppler shift of the reflective radar frequency Radar frequency for X band is - Correct Ans-10.525 GHz Radar frequency for K band is - Correct Ans-24. 150 GHz Radar frequency for K a band is - Correct Ans-33.4 to 36 ghz Do you transmitted frequency for radar is - Correct Ans-Consistent Being length is infinite unless - Correct Ans-Reflected absorbed or refracted Where X equals with D equals the distance and < equals the angle formula for measuring beam width is - Correct Ans-X=2D(TAN<1/2) The maximum effective range of radar - Correct Ans-800-4500 Ft. And varies according to model position and manufacture capability This just the radars sensitivity - Correct Ans-Range control adjustment Doppler shift in X-band for 1MPH is - Correct Ans-31.389 CPS Doppler shift in K-band for 1MPH is - Correct Ans-72.023 CPS Doppler shift in KA-band for 1MPH is - Correct Ans-104 CPS Radar measures the patrol car speed approximately - Correct Ans-100-150 Ft. In front of the patrol vehicle Patrol vehicle speed is computed from the radars - Correct Ans-Patrol Doppler or Low Doppler Closing rate speed is computed from the radars - Correct Ans-High Doppler In moving radar the ____ - ______ = the target speed - Correct Ans-Low Doppler - high doppler Radar angular effect is referred to as the - Correct Ans-Cosine effect The _____ occurs when a target enters the radar beam at an angle - Correct Ans-Cosine effect Moving costume effect may show an indicated target speed ____ or higher than the targets actual speed - Correct Ans-Lower Interference is typified by - Correct Ans-A. Lack of supported evidence B. Weak signal C. Inconsistent audio tone D. Momentary in nature Sudden changes in patrol car speed can cause - Correct Ans-Batching When the radar mistakes a slower moving vehicle for ahead of the patrol vehicle for the roadway - Correct Ans-Shadow effect Rapidly moving the antenna will cause the radar to mistake stationary landscape for the target. This is called the _____ effect. - Correct Ans-Scanning The _____ effect is caused by pointing the antenna at the counting unit. - Correct Ans-Feedback Tracking history for stationary mode includes: - Correct Ans-A. Target vehicle in beam B. Visual estimation C. Audio Doppler D. Confirm with radar unit Tracking history for moving mode: - Correct Ans-A. Target vehicle in beam B. Visual estimation C. Audio Doppler D. Confirm with radar unit
