PRECISE MEASUREMENT AND TRACKING OF DISTANCE FOR SPARSE-ARRAY SYNTHETIC IMPULSE AND APERTURE RADAR
-
摘要: 本文针对稀布阵综合脉冲孔径雷达(SIAR)提出了两种精密测距方法(分别称为正负频率脉冲综合法和前后脉冲综合法),它们不需要提高采样频率就可以得到较高的测距精度;讨论了时空三维匹配滤波时角度误差对测距的耦合影响;介绍了其跟踪处理过程;并通过计算机仿真证明了这两种方法的有效性。Abstract: Two methods of distance measuring for sparse-array Synthetic Impulse and Aperture Radar(SIAR) are described, by which a high precision is obtained without high frequency sampling. The effect of errors in angle measuring on distance measuring is discussed in the process of time-space 3D matched filtering. Computer simulation results show these methods are effective.
