| 摘 要： | 针对常规窄带雷达无法直接在距离和方位上识别目标架次的缺陷，利用编队目标间距引起的多普勒频率的差异，给出了一种基于时频分析的窄带雷达目标架次识别方法．该方法既有良好的时频分辨特性，同时又能抑制交叉项，因而能对目标架次做出准确的判断．计算机仿真结果验证了该方法的有效性．

| Abstract: | Aimed at the drawback that the conventional narrow-band radars could not identify the target sorties directly over the range and azimuth, this paper presents an identification method for the target sorties of narrow-band radars based on time-frequency analysis, by taking advantage of the Doppler frequency difference resulted from the space between formation targets. This method has the better time-frequency resolution characteristics and can also suppress the cross-terms simultaneously, thus being able to make correct decision on target sorties. Computer simulation results prove this method to be of effectiveness. |
