一种混合噪声调制的毫米波脉冲多普勒雷达原理

Principle of Millimeter PD Radar Modulated by the Mixed noise

提出了一种新型的噪声毫米波脉冲多普勒雷达，即随机脉冲位置调制与脉冲之间随机相位调制相结合的毫米波脉冲多普勒雷达。首次给出了该随机序列的模糊函数数学表达式。给出了其系统原理框图，分析了其工作原理和数学模型，研究了它的抗干扰特性。分析表明，它具有良好的抗干扰特性，同时不会出现距离速度模糊，是一种较佳的毫米波脉冲多普勒雷达。

In this paper a novel type of millimeter noise PD radar is presented, which is the mil-limeter PD Radar modulated by randomly staggered pulse sequence whose phase is also randomly modulated.The expression of its ambiguity function is firstly presented,the block diagram of the system is given, the working principle,mathematical model and its performances of anti-jamming are analyzed. The analysis in theory shows that it can provide good performances of antui-jamming and avoid the ambiguity of the distance and velocity,so it is one of the millimeter bet PD radar.
