摘要
在雷达信号分选时,一般的思路是采用到达时间、脉宽、频率、到达方向等参数对信号进行分选,分选完成后再将同一辐射源的脉冲幅度提取出来,进行雷达扫描特性等分析。对某实际采集数据进行了分析,发现信号的时间、幅度曲线有明显的规律,采用了抛物线霍夫变换提取了全脉冲的幅度特性,并采用时间、幅度联合分析完成了信号的分选。仿真结果表明了该方法的有效性,为雷达信号分选提供了一条新的思路。
In radar signal sorting,the general idea is to use the time of arrival,pulse width,frequency,direction of arrival and other parameters of the received signal.After signal sorting,the amplitude of the same emitter is extracted to analyze the characteristics of radar scanning etc.The certain collected actual data is analyzed,and it is found that the time-amplitude curve had obvious regularity.The parabola Hough transform is used to extract the amplitude regularity of the pulse,and the combined analysis of the time and amplitude is adopted to complete signal sorting.Simulation results show the effectiveness of the presented method,and a new idea for radar signal sorting is provided.
