Harmonic Detection and Suppression of Frequency Doubling of Speed Measuring Radar Based on Closed-Loop Gain Control

Abstract:

This paper investigates the problem of frequency doubling with speed measuring radars. The main reason for it is that the gain of the reflected wave receiver cannot cope with all the possible waves reflected by cars of different distances away from the radar. Strong signals will saturate the receiver and generate harmonics which interferes with the speed measuring. Based on this, a harmonic detection and frequency doubling suppression method is developed in this paper and the effectiveness of the method is verified by experimental results.
