摘　　要：针对雷达接收机和雷达对抗侦察接收机存在的不同特征,提出了基于信号重构的雷达与雷达对抗侦察一体化接收技术。首先利用复指数调制滤波器组将中频带宽分解为若干子带,再通过频谱感知和信号重构实现非均匀动态信道化,最后利用非均匀动态信道化技术分别接收雷达回波信号和辐射源直射信号。为了满足一体化接收机的瞬时动态范围、灵敏度、监视带宽以及频率分辨率等性能指标的要求,引入一种大值高阻带衰减原型滤波器设计方法。理论分析和仿真实验验证了该一体化接收技术的有效性。An algorithm of sub-band processing matched filter to wideband radar echo based on sub- band processing in receiving structure based on measure reconnaissance is proposed. In this alg sign orith al reconstruction integrated radar and radar counter- m sub-band matched filter coefficients can be formed when transmitter waveform passed analysis filter banks. The problem of radar bandwidth wider than sub- of receiver integrated radar and radar countermeasure reconnaissance can be resolved as matched fil- ter to radar echo by sub-band processing. The countermeasure reconnaissance can be realized band width of inte ty of this matched grated filter receiver technology integrated wideband radar and radar because the bandwidth of radar is not decided by sub- receiver. Theoretical analysis and computer simulation have illustrated the validi- algorithm based on sub-band processing
