降低稀布阵综合脉冲孔径雷达距离旁瓣的方法研究

The low-range-sidelobe technique for sparse-array synthetic impulse and aperture radar

稀布阵综合脉冲/孔径雷达(SIAR)采用多个频率信号同步发射以实现各向同性照射.文中针对该雷达由于频率间耦合而存在较大的距离旁瓣,提出脉间(或脉组)频率编码捷变的方法来降低距离旁瓣;分析其机理和对杂波抑制的影响;通过计算机模拟证明了该方法的有效性.

The sparse-array synthetic impulse and aperture radar(SIAR)can give isotropic radiations by employing multiple frequencies(synthetic pulse)and multiple antennas(synthetic antenna).A method to reduct its range sidelobes with frequency-coding agility among these frequencies is presented.Computer simulation results show that the method is effective.
