Pulsed doppler radar ( pd radar ) is a kind of advanced radar which using coherent processing 脉冲多普勒雷达是一种先进的全相参体制雷达。
In this paper , the application of coherent phase - coded pulse train ( cpcpt ) solves range - doppler coupling well 应用相参频率编码脉冲串信号( cpcpt )较好地解决了距离-多普勒耦合问题。
And then , associated with the subject ' s requirement and the realistic conditions , the system proposal is confirmed 然后根据现实条件和课题需要确定了ka波段相参收发前端的系统方案。
Based on the method , exploiting the coherent property of pulse train , the accurate estimation of signals is obtained 以该算法为基础,结合相关谱和脉间相参信息,得到正弦脉冲信号频率的精确估计。
To implement effective jamming on the modem coherent radar , this paper proposes one smart noise jamming realization scheme based on convolution modulation 摘要为了对现代新体制相参雷达实施有效的干扰,提出了一种基于卷积调制的灵巧噪声干扰技术实现方案。
The dissertation mainly focuses on the theory and design of ka - band coherent transceiver front - end , and the transceiver front - end design , assembling and testing are also given 本文主要对ka波段相参收发前端的理论进行了研究,并进行了系统样机的设计、制作与测试。
As for mm - wave radars , they generally require frequency sources of full - coherence 、 high spectrum pureness and frequency - agile ability 。 this task was carried out just aiming at high ? performance mm - wave sources 本课题即是为研制低相噪、低杂散、窄步进、捷变频的全相参毫米波频率源而开展的。
This kind of jamming not only could avoid the process of coherent radar for blanket jamming to improve the utility of jamming power , but also own better jamming effect than pore deception jamming 这种干扰不仅消除了相参雷达对压制干扰的处理增益,以提高干扰功率利用率,同时又比纯欺骗干扰具有更好的干扰效果。
Implementations of video integrators , which are based on two - pole filter , are discussed in the last . the initialization , tail and noise integrating problems are analyzed and improvements are given 最后,本文对非相参视频积累器的实现进行了讨论,分析了双极点滤波器存在的初始化、拖尾和噪声电平问题,并提出了改进的方法。
So this technical may improve the detecting performance . the relation between radar target _ detecting based on the radar ppi and radar t _ r system , singnal processor system is very little which is good to modify the old radar 另外,基于ppi的雷达目标检测与雷达收发系统、信号处理系统的直接关系不大,这对于老式非相参雷达的数字化改造十分有利。
