稀布阵综合脉冲孔径雷达的四维模糊函数及其分辨率

4-Deminsional Ambiguity Function and Resulotion of Sparse-Array Synthetic Impulse and Aperture Radar

稀布阵综合脉冲孔径雷达（SIAN）是一种崭新的四坐标（距离、方位、仰角和速度）雷达，它采取全向发射工作方式而不采用传统的波束扫描，因而具有四维模糊函数。本文推导了它的四维模糊函数，分析了其分辨能力，给出了圆形阵列的波束宽度的计算公式。最后简单介绍了它的四维匹配滤波处理。

Sparse-array Synthetic Impulse and Aperture Radar (SIAR) is a novel 4-dimentional radap which can isotropicly radiate without beam spanning. In this papet, The 4D ambiguity function and resolution of SIAR are described, and the calculative formula of circulararray beamwidth is provided. Finally, the 4D matched filter is given in brief.
