Radar signal processing method, especially for pulse Doppler vehicle distance radar

摘要

The measuring process is divided into several successive intervals and each interval into cells and the individual cells defined by the parameters characterising the radar signals to be detected. The method employed is the cell averaging process and average values for interference power are derived from the measurements on individual cells. To prepare for constant false alarms, the process is enhanced by means of ordered statistics, the OS-CFAR method. The interference has to be adapted to the target and an estimate of the interference is selected as a basis for the calculations.
