radar pulse compression
Examples
- The fast development of digital signal processing technology provides us with the possibility of numeralization of radar pulse compression processing
同时,数字信号处理技术的迅猛发展和广泛应用,为雷达脉冲压缩处理的数字化实现提供了可能。 - In this paper , firstly , radar pulse compression is introduced briefly , summarize three primary pulse compression signals : lfm , nlfm , pcm
本文首先对雷达脉冲压缩的原理作了简要的介绍，进一步详细分析了应用最广泛的线性调频信号，并简要介绍了非线性调频信号和相位编码信号。 - Linear frequency modulated ( lfm ) signals as the most popular pulse compression signal are a typical kind of time - varying , nonstationary signals , so applying the wigner - ville distribution into lfm signals has more advantages than conventional methods
雷达脉冲压缩技术中所使用的线性调频信号是一类典型的时变非平稳信号，采用时频分析的研究方法处理线性调频信号有着传统方法无法比拟的优点。 - Finally , based on the analysis of the stastistical characteristic of the range sidelobe ( rsl ) after the pulse compression accumulation of the rppm pd radar , one method has been brought forward to decrease the rsl and increase the ratio of the mainlobe to the sidelobe using fft and some simulations also have been acquired
最后在分析了随机脉位调制脉冲多普勒雷达脉冲压缩积累后距离旁瓣的统计特性基础上，提出了采用fft处理方案抑制距离旁瓣来提高主旁瓣比的方法，并给出了一些仿真结果。
