目前正在研制一种合成天线的相干侧视(距离——方位)雷达的天线方向图和传输信号的设计方法。一般的设计规范是,在限定的有限天线孔径和信号带宽下最大限度地减少模糊函数的假响应。任何这种相同的抑制设备所遇到的问题都已圆满解决。孔径尺寸与距离及方位分辨率之间的相互作用,以及最佳设计中产生的假响应级都已示出。天线孔径照射,信号幅度和相位调制以及相位重复频率也都有了规定。
An antenna pattern and transmission signal design method of a coherent side-looking (range-azimuth) radar for synthetic antennas are currently being developed. The general design specification is to minimize the false response of ambiguity functions with a limited finite antenna aperture and signal bandwidth. The problems encountered with any such same suppression device have been satisfactorily solved. The interaction between aperture size and distance and azimuth resolution, as well as the fake response levels produced in the best designs, have been shown. Antenna aperture irradiation, the signal amplitude and phase modulation and phase repetition frequency are also provided.
