PRINCIPLE OF MILLIMETER PULSE DOPPLER FUSE MODULATED BY MIXED NOISE
【摘要】 提出了一种新型的噪声毫米波脉冲多普勒引信,即随机脉冲位置调制与脉冲之间随机相位调制相结合的脉冲多普勒引信。推导了该随机序列的工均模糊函数,给出了该引信原理实现框图,分析了其工作原理和数学模型,研究了它的抗干扰特性和可实现性。分析表明,该引信可以避免距离速度模糊,具有良好的抗干扰特性,是一种较佳的毫米波脉冲多普勒引信。
【Abstract】 A novel type of noise PD fuse is presented, viz- a millimeter PD fuse modu-lated by the pulse sequence whose position and phase are random. Its average ambi-guity function is derived. The block diagram of the system is given. The working prin-ciple and its mathematical model are analyzed and the practicability as well as perfor-mances of anti-jamming are studied. Analysis in theory shows that the fuse can provide good performance of anti-jamming and avoid the ambiguity in distance and velocity,showing that it is one among the more desirable variaties of pulse doppler fuses.
【Key words】 noise fuse; randomly staggered pulse sequence; random binary-phase code; average ambiguity function;
