本文从抗信号载获出发,研究了具有大时宽带宽积的二相编码序列波形,确立了以雷达“MT1-脉冲压缩-非相参积累”处理方案相结合的信号波形优化准则.根据这一信号波形优化准则,在计算机(?)量模块拟研究基础上,给出了码长 P=127的二相编码序列波形优化实例.当回波引入多普勒频移 f_d在0～10 kHz 变化时,这种信号的非相参积累输出,其主付比均达到实用要求,这种信号又容易实现脉间波形捷变,使信号具有良好的抗干扰和抗截获获能力,满足了中程搜索雷达对信号的要求.
In this paper, from the anti-signal acquisition, the two-phase coded sequence waveforms with large-time and wide-bandwidth products are studied, and the signal waveform optimization criterion based on the combination of MT1-pulse compression and non-coherent accumulation is established. A signal waveform optimization criterion is given on the basis of the computer (?) Module, and an example of two-phase code sequence waveform optimization with code length P = 127 is given. When the echo is introduced into the Doppler shift f_d between 0 and 10 kHz Changes, the non-coherent accumulation of such signals output, the ratio of their main meet the practical requirements, this signal is easy to achieve pulse-pulse agility, so that the signal has good anti-interference and anti-interception ability to meet the Cheng search radar signal requirements.
