Constant false alarm rate detection method based on background discrimination

The invention belongs to the field of radar constant false alarm detection, and relates to a constant false alarm detection method based on background discrimination. According to the method, the thought of deleting constant false alarm detection is adopted, the detection probability under the target shielding condition is ensured, and the detection probability under the target shielding condition is higher. The clutter separation point is calculated in the full detection range, the stability of the false alarm probability near the clutter demarcation point is further improved, and the detection performance is improved. Different detection strategies are adopted under different conditions, target detection under the multi-target interference condition can be achieved, and the stability of the false alarm probability at the clutter edge is improved. 本发明属于雷达恒虚警检测领域，涉及一种基于背景判别的恒虚警检测方法。本发明方法采用删除恒虚警检测的思想，保证了目标遮蔽情况下的检测概率，使得本发明对于目标遮蔽情况下的检测概率更高。本发明在全检测范围内计算杂波分离点，进一步提高了杂波分界点附近虚警概率的稳定性，提高了检测性能。在不同的情况采用不同的检测策略，本发明的方法可以实
