| 摘 要： | 首先分析了编队目标间距引起的目标间多普勒频率的差别以及多普勒频率的变化规律，建立了高速运动的编队目标回波信号的数学模型，详细分析了利用Morlet小波变换提取目标数量、多普勒频率等信息的方法，该方法不仅取得了对编队目标的高分辨率，同时计算速度快，数据量小，且对噪声干扰不敏感，有利于实现实时编队目标信号处理；最后给出计算机仿真结果，验证了其可行性和有效性。

| Abstract: | The Doppler frequency difference between objectives caused by the distance of the formation targets and the Doppler frequency regularity is firstly analyzed, and then how to get the amount and the Doppler frequency of the objects using Morlet wavelet is analyzed in brief. A conclusion is drawn out that the wavelet transformation method is optimal not only to get high resolution performance, but also to implement the real-time signal processing for multi-objects in formation because of its high resolution, quick calculation, a small quantity of data to deal, and noise interference rejection. In the end, the computer simulation is supplied to show the feasibility and effectiveness. |
