【摘要】：为实现任意阵列天线的方向图综合,特别是考虑到不同空间指向对阵列方向图的影响,提出自适应原理与凸优化理论相结合的方向图综合法。该方法首先利用自适应原理综合法得到所需阵列方向图的旁瓣特性;而后,选择零度角的方向图主瓣作为期望主瓣;最后,在该期望主瓣响应下,将阵列方向图综合问题转化为二阶锥规划问题。采用凸优化循环迭代算法,完成对非凸优化问题的求解,从而保证方向图在满足期望主瓣响应的同时,使旁瓣特性与自适应方向图综合方法得到的结果最接近。理论分析与仿真结果表明,综合后阵列方向图在不同空间指向上具有与期望主瓣一致的主瓣特性,且其旁瓣也能够很好地保持对动态干扰的抑制特性。
[Abstract]:For the realization of arbitrary array antenna pattern synthesis, especially considering the different influence on the spatial point array, pattern synthesis method is proposed based on the theory of adaptive principle and convex optimization. This method uses the sidelobe characteristics synthesis method to obtain the required principle of adaptive array; then, select zero angle mainlobe as the desired mainlobe; finally, the desired mainlobe response, the array pattern synthesis problem into two second-order cone programming problem. By using convex optimization iteration algorithm, the non convex optimization problem solving, so as to ensure the direction map in satisfies the desired mainlobe response at the same time, the sidelobe characteristic and adaptive direction map synthesis method. Results close to the theoretical analysis and simulation results show that the comprehensive array pattern in different spatial distribution characteristics of main lobe with a main lobe consistent with expectations And its sidelobe can also maintain the suppression of dynamic interference very well.
