本文提出了一种对小间隔的点目标进行测量的方法。这种方法既利用了时域阶矩,又利用了频域阶矩。玻姆(Baum)的方法只是本文所述方法的一种特殊情况,文中所阐述的测量方法,并不以点目标的间隔应比波形分辨力大为前提。所以,点目标之间的距离虽小于瑞利极限,仍能进行测量。因为这个计算法以单个脉冲信息为基础,所以,该方法特别适于实时信号处理。为了证明这个方法的可行性,本文给出了数字模拟结果。 This paper presents a method of measuring small-spaced point targets. This method not only exploits the time-domain moments but also takes advantage of the frequency-domain moments. The Baum method is just a special case of the method described in this article. The measurement method described in this article does not presuppose that the spacing of the point targets should be greater than the resolution of the waveform. So, although the distance between point targets is less than the Rayleigh limit, measurements can still be made. Because this algorithm is based on single pulse information, this method is particularly suitable for real-time signal processing. In order to prove the feasibility of this method, this paper gives the numerical simulation results.
