信号稀疏表示的目的就是在给定的超完备字典中用尽可能少的原子来表示信号，可以获得信号更为简洁的表示方式，从而使我们更容易地获取信号中所蕴含的信息，更方便进一步对信号进行加工处理，如压缩、编码等。信号稀疏表示方向的研究热点主要集中在稀疏分解算法、超完备原子字典、和稀疏表示的应用等方面。(Signal sparse representation is to overcomplete dictionary given in as little as possible to represent atomic signal, signal can be more succinct representation, which makes it easier for us to get there in the signal information, more convenient for further signal processing, such as compression, encoding etc.. The focus of research on signal sparse representation focuses on sparse decomposition algorithm, ultra complete Atomic Dictionary and sparse representation.)

本文首先介绍了近些年来雷达模拟器获得广泛应用及其原因，然后对目标模 型、杂波模型和机载下视脉冲多普勒雷达的频谱分布进行了分析。接着，研究了 雷达回波信号模拟的实现方法，重点是采用网格映象法对地杂波信号的模拟进行 了分析和推导，并采用此方法对瑞利分布的高斯谱杂波、雷达回波信号进行了仿 真和分析。最后，针对用于某机载雷达信号模拟器系统的数字信号处理器进行了 设计和分析。 (This paper first introduces the radar simulator in recent years is widely available and the reasons for, and then on the target model, and the clutter model of airborne pulse Doppler radar, as under the spectrum distribution is analyzed. Then, to study radar signal simulation methods, with emphasis on the use of grid mapping method to the simulated clutter signal analysis and derivation, and use of this method, the Gaussian distribution of the Rayleigh spectrum of clutter, the radar echo signal simulation and analysis. Finally, for an airborne radar signal simulator system digital signal processor has been designed and analyzed.)
