| 摘 要： | 研究一种新型伪噪声雷达信号波形,该波形采用了多个脉冲组,每组脉冲中调相的伪码相同,相邻组内的脉冲调相所用的伪码捷变,同时每个脉组内的各脉冲频率捷变。理论推导和仿真分析了这种雷达信号波形的模糊函数,仿真结果表明这种信号具备良好的距离和速度分辨力及低截获概率,能测高速和远距离目标,工程上也易于产生和处理,具备良好的应用前景。

| Abstract: | A new PN radar waveform is proposed in this paper,which adopts a few pulse groups,the pseudorandom codes used to modulate phase in every group pulse are the same,while they varies between groups,and the carrier frequencies which are selected randomly from the given frequencies vary among pulses in every pulse group. The average ambiguity function of the waveform is derived in theory,simulation indicates that the radar signal possesses good range resolution,velocity resolution and LPI (low probability of int... |
