摘要
步进频连续波雷达采用频率步进的连续波雷达发射波形,具有较高的距离分辨率。依据线性调频连续波雷达的二维快速傅里叶变换(FFT)算法和连续波频域测速理论,对步进频连续波雷达的目标识别方法进行了改进,实现了对多目标的识别,进行了仿真。结果表明该算法有效可行,具有较好的测距精度。
The transmitting waveform of continuous-wave radar based on stepped frequency is used for stepped frequency continuous wave radar,which is provided with relatively high range resolution.Based on two-dimensional fast Fourier transform（FFT）algorithm and speed measuring theory in continuous wave frequency domain of linear frequency modulation continuous wave radar,this paper improves the target identification methods based on stepped frequency continuous wave radar,realizes the multi-target identification,performs the simulation.Results show that the algorithm is effective and feasible,and has superior range measuring accuracy.
