Research on the multiple arrays splicing Radar pattern optimization
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,in-creasing the antenna aperture of the radar must not only consider the physical structure limita-tions of the carrier 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 side-lobe of the spliced array pattern,the relationship between the array spacing and the synthesis pat-tern 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 optimiza-tion algorithm is used to suppress the side lobe of the synthesis pattern,and the correctness of the proposed method is verified by simulation experiments.
