稀布阵综合脉冲孔径雷达发射信号频率编码的研究

Study of Frequency Coding of Transmitting Signals for Sparse-Array Synthetic lmpulse and Aperture Radar

稀布阵综合脉冲孔径雷达（ＳＩＡＲ）是一种新型米波四坐标雷达．它工作在跟踪方式时，通过时空三维匹配滤波分别形成距离和－差通道和方位、仰角跟踪波束，必然会存在相互之间由于测不准而产生的耦合影响．本文首先讨论该耦合影响，然后提出一种克服该影响的优化各阵元发射信号频率编码准则，从而便于实时跟踪目标的四维坐标．

The sparse-array Synthetic Impulse and Aperture Radar(SIAR)is a new type of4D radar using metric wavelengths. The coincidence effects between distance and angles are discussed existing in the different-sum channel of distance and the tracking beams of azimuth and elevation formatted by time-space 3D matched filtering. The optimized frequency coding of the transmitting signals is presented in order to delete the effects.
