针对被动声呐弱目标检测问题，提出一种基于子频段的弱目标的检测方法。该方法把子频段峰值能量检测和Eckart后置处理滤波器相结合，对波束形成后的子频段谱进行Eckart加权，从而提高强干扰下的弱目标检测能力。仿真实验和海试数据分析验证了该方法的有效性。
In order to enhance the capability of weak target detection, a method based on sub-band peak energy detection for weak target detection is proposed. The method combines the sub-band peak energy detection and Eckart filter, which uses the Eckart equation to define the weight value and the sub-band spectrum is weighted by it. The proposed method can increase the performance of weak target detection in shallow water with multi-strong interferences. Simulation and sea trials prove its validity and superiority.
