| 摘 要： | 当雷达间距离过于靠近时,可能存在着相互干扰。针对线性调频信号形式简单,易受到其他雷达信号和噪声干扰特点,提出了一种脉内线性调频和子脉冲相位调制相结合的具有多种变化形式的混合调制脉冲压缩信号。然后介绍了几种典型的雷达信号和噪声干扰信号及其表达形式,研究该混合调制信号受到它们的干扰问题,通过仿真分析表明,该混合调制信号具有较强的抗干扰性能。

| Abstract: | When the distance is overly neared among the radars,may be interfered with each other.Because of simple form of linear frequency modulation signal,it is easily to be interfered with the characteristics by other radar signal and noise,variable co-modulated pulse compression signal combining pulse linear frequency modulation to sub pulse phase modulation is proposed.Then several kinds of typical radar signals and noise interfering signals and expressed form are introduced,studying the co-modulated signal is interfered with the problem by them,through simulation analysis,the co-modulated signal has strong anti-jamming performance. |
