Radar constant false alarm detection threshold adaptive setting method

The invention relates to a radar constant false alarm detection threshold adaptive setting method. According to the method, different detection threshold coefficients are set for different areas, a quite high detection threshold is set in a strong-cluster area so as to realize the purpose of reducing false alarm, and at the same time, a quite low detection threshold is set in a weak-cluster area so as to improve the detection efficiency of the area. From the perspective of a whole radar detection area, the detection performance of a radar is greatly improved. 本发明涉及种雷达恒虚警检测门限自适应设置方法，该方法可对不同区域设置不同的检测门限系数，从而在强杂波区域设置较高的检测门限，已达到降低虚警的目的，同时在弱杂波区域设置较低的检测门限，以提高该区域的检测概率。从雷达整个检测区域考虑，雷达的检测性能得到较大改善。
