摘　　要：增大雷达天线的孔径是提升雷达探测距离、测角分辨率和测角精度最直接的方法。但是增大雷达的天线孔径除了需要考虑载体平台的物理结构限制之外,还必须要考虑对雷达机动性的影响。为兼顾雷达的机动性、雷达的威力和测角分辨力,考虑将多个可便携的阵面拼接合成一个大阵面,为避免拼接后的方向图产生高副瓣,首先对阵面间距与合成方向图栅瓣产生关系进行研究,接着在阵面间距保证阵面不会出现栅瓣条件下,使用凸优化算法对拼接后方向图的高副瓣进行抑制,并通过仿真试验验证了本文方法的正确性。Increasing the aperture of the radar antenna is the most direct way to improve the radar detection distance,angle measurement resolution and angle measurement accuracy.However,increasing the antenna aperture of the radar must not only consider the physical structure limitations of the carricr platform,but also consider the impact on the maneuverability of the radar.In order to take into account the maneuverability of radar,the power of radar and angle resolution,consider the splicing of multiple portable arrays to a large array,in order to avoid the high sidelobe of the spliccd array pattern,the relationship betwecn the array spacing and the synthesis pattern grating lobe is studied,and then under the condition that the spacing between small portable arrays ensures that the synthesis pattern does not appear high grating lobe,the convex optimization algorithm is used to suppress the side lobe of the synthesis pattern,and the correctness of the proposed method is verified by simulation experiments.
