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.)

本文针对并行干扰抵消检测器的不足之处，提出了改进的并行干扰抵消检测算法——基于多项式展开的并行干扰抵消多用户检测算法。该算法将多项式展开检测器作为并行干扰抵消检测器第一级的数据估计值，以提高检测可靠性。通过仿真实验，首先验证了多项式展开检测器的性能。然后比较改进算法与传统检测器的性能，验证改进算法的系统性能得到明显改善；并与并行干扰抵消检测器、解相关检测器和MMSE检测器相比较，验
证得到该改进算法的性能也有不同程度的改善。
(this paper discusses the principle and performance of the
conventional detector and the parallel interference cancellation(PIC)detector
separately.Since the conventional detector take MAI only as the background noise without considering the existence of the other users,the existence of MAI has a significant impact on the performance of CDMA systems.Each stage of PIC detector utilizes the data estimates of the initial or previous stage,produces a new set of MAI estimates,and then subtracts out all of the MAI for each user in parallel.Through Monte Carlo simulation in different scenarios,the results illustrate the influence of MAI in conventional CDMA ystems.Theexperimental results show PIC detector can effectively eliminate MAI andimprove the system BER.
