Abstract
A method is proposed for use on a coherent Doppler radar system for the purpose of reducing the clutter and mutual interference in the coherent Doppler radar system. The echoed radar signal from the target object is converted into a Range-Doppler Domain output signal. If the Range-Doppler Domain output signal indicates the presence of mutual interference, a Crisscrossing CFAR method is selected to compute for the CFAR back-ground value; otherwise an Area CFAR method is selected. A target-detection logic circuit is then used to obtain the radar information about the target object. By the proposed method, the output signal of the target-detection logic circuit is substantially free from clutter and mutual interference, which is further converted into a radar display signal to drive a radar display unit to display the location and velocity of the target object.
