PRECISE MEASUREMENT AND TRACKING OF DISTANCE FOR SPARSE-ARRAY SYNTHETIC IMPULSE AND APERTURE RADAR
稀布阵综合脉冲孔径雷达目标距离的精密测量和跟踪

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.
