| 摘 要： | 本文从最佳检测理论和高分辨率雷达目标回波特征出发,将目标上各散射点形成的在时域上分离的回波看成具有随机参量的脉冲串信号,提出了适用于高分辨率雷达目标单次回波检测的随机参量脉冲串(RPPT)检测方法.计算机仿真结果表明,在高分辨率雷达中,这种检测方法比雷达经典检测方法有2dB以上的检测性能改善.

| Abstract: | By treating time domain separated echoes,caused by the scatters on the target,as a pulse train with random parameters,a new detection method is proposed for high resolution radar target detection based on the theory of optimum detection and the characteristic of target's echoes in a high-range-resolution radar.Computer simulation shows that the new method has at least 2dB improvement in detection performance compared with the traditional detection method. |
