A study of lowering the peak SLL of shared aperture radar arrays is presented. A two-weight amplitude distribution for the elements of transmit and receive arrays is used. Imposing certain conditions, the relation of the number of elements of the arrays was found. One condition imposes the appearance of a minor lobe position of transmit or receive array pattern at a certain null of receive or transmit array pattern. A second condition imposes the equal sidelobe level of two consecutive minor lobes either near the main beam of the two-way array pattern or at certain positions of receive or transmit array pattern. The resulting peak SLL of the two-way radar array pattern depending on the conditions reaches from −47 dB up to less than −50 dB.

降低共享孔径雷达阵列中双向波瓣的旁瓣水平

提出了降低共享孔径雷达阵列的峰值SLL的研究。对于发射和接收阵列的元素，使用了两个权重的幅度分布。通过施加某些条件，发现了数组元素数量的关系。一种情况是在接收或发送阵列模式的某个零值处出现一个较小的发送或接收阵列模式的瓣位置。第二种条件是在双向阵列图案的主波束附近或在接收或发射阵列图案的某些位置处施加两个连续的副瓣相等的旁瓣电平。取决于条件的双向雷达阵列模式的最终峰值SLL从-47 dB到小于-50 dB。
