摘　　要：基于k/m准则的二进制滑窗积累器具在检测性能上具有较大的局限性,研究使用三电平滑窗积累器对检测性能的改善。三电平滑窗积累器在幅度量化时采用多个电平以提高量化精度,所以改善了对信号特别是弱目标信号的检侧性能。重点分析了这种改进型滑窗积累器的性能。There are several limits by using the two segment slide-window integrator based on the k/m-rule. This paper considers the three-level slide-window integrator, and analyses the performances on detection of it. By using the three-level to enhance amplitude quantization accuracy, the detection performance of signal, especially weak target signal can be improved with the multi-level integrator. This paper lays special stress on the performance of this improved integrator.
