Beschreibung
Zusammenfassung:	The invention relates to an outer radiation source radar Doppler-time delay two-dimension double-threshold object detection method comprising the following steps: firstly, a reference antenna and an echo antenna respectively receive base station emitted a direct wave signal and a motion object echo signal; then, carrying out interference cancellation and coherent accumulation processing in sequence for the echo signal received by the echo antenna; finally, using a Doppler-time delay two-dimension double-threshold false alarm algorithm to carry out object detection. The method mainly solves object detection high missed alarm and false alarm problems under a strong interference residual environment, can realize object detection under the strong interference residual condition, and is low in missed alarm probability and false alarm probability.
