采用遗传算法的MIMO雷达L型阵列稀布优化
L-shape Sparse Array Optimization Based on Genetic Algorithm in MIMO Radar
摘要
Abstract
In order to avoid the grating lobe effect in multiple-input multiple-output( MIMO) radar caused by array sparse distribution,a synthesis and optimization algorithm of L-shape sparse array in MIMO radar is proposed. Two-dimensional pattern synthesis is achieved with L-shape sparse array in MIMO radar which is equivalent to virtual rectangular plane array. Both the transmitting and receiving antenna array ge-ometries are optimized through introducing a random perturbed variable,so that the grating lobe can be sup-pressed and two-dimensional pattern synthesis with lower relative sidelobe levels in both azimuth and ele-vation dimensions can also be obtained. In the proposed method,mutation operation in classic genetic algo-rithm is modified to enhance the global search capability. Simulation results indicate the validity of the pro-posed methods.关键词
