摘要
Abstract
For the complex multi-target environment of continuous-emission artillery,the CA-CFAR processing method can′t meet the requirement of signal detection. In order to make full use of the moving information of the target,the distance-Doppler two-dimensional CFAR method is used to estimate the background noise. The modified CA-CFAR processing is adopted to elimi-nate the mutual interference among the targets. The dual-threshold detection is combined to further process the multi-target echo of continuous-emission artillery. The dynamic threshold is introduced to enhance the detection robustness. The engineering prac-tice result shows that the method can improve the signal-to-noise ratio and signal-to-clutter ratio of the echo signal,realize the con-tinuous-emission artillery multi-target detection effectively,and provide the basis for the target parameter extraction of next step.关键词
