摘　　要：平均选大恒虚警率检测算法是一种比较成熟的检测算法,但是在干扰环境、杂波环境以及多目标环境中,检测门限会提高,使得检测性能下降。改进了平均选大恒虚警率检测算法,提出了一种双参数恒虚警率检测算法,仿真结果表明:此种算法可以提高在干扰环境、杂波环境以及多目标环境下的检测性能。Average greatest of constant false-alarm rate(CFAR)detection algorithm is a relatively mature detection algorithm,but the detecting threshold may increase in the jamming environment,clutter environment and multi-target environment,which makes the detecting performance decrease.This paper improves the arerage greatest of CFAR detection algorithm,puts forward a two-parameter CFAR detection algorithm.The simulation results show that this algorithm can increase the detection performance in the jamming environment,clutter environment and multi-target environment.
