Radar clutter map detection threshold adaptive setting method

The invention relates to a radar clutter map detection threshold adaptive setting method which can set different detection threshold coefficients for different regions so as to set a high detection threshold in a strong clutter region for a purpose of reducing false alarms, and to set a low detection threshold in a weak clutter region for improving the detection probability of the weak clutter region. The method takes the whole detection region of the radar into consideration so as to greatly improve the detection performance of the radar. 本发明涉及种雷达杂波图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。
