利用Matlab软件工具，对简单的植被形态进行模拟，模拟结果生动逼真。首先，迭代产生一系列字符串；其次，根据将L系统与图形联系起来，采用龟形的概念赋予每个字符特定的图形含义；最后，读取字符并画图，根据读取到的字符通过Matlab实现相应的操作。(According to L system and iterated algorithm, shape of trees were simulated with matlab functions and programs and the fractal trees’ configurations were natural and living. First, we use iteration to produce a series of string. Then, connecting the L system with graphs, we use the theory of turtles to give each character a specific meaning. Finally, read the string and draw pictures with the matlab. )

雷达通信一体化系统，针对非波动目标以及波动目标的雷达探测性能分析。(he dual-frequency MPPSK-MODEM platform is a flexible one. When ranging accuracy request is low or platform is particularly affected by power limitations, the platform would perform both data transmission and range measurement with single frequency modes. In this paper, the ranging resolution of MPPSK pulse waveforms with the match filter and impacting filter processing method are discussed, respectively. Also, the selection of MPPSK modulation parameters for ranging is considered. In particular, requirements that allow for employing such special parameter values for range measurements with high accuracy and high range are investigated. Moreover, high repetition frequency (HRF) bi-phase code MPPSK pulse train base on m sequence are presented, the ranging accuracy of the proposed signal with the match filter processing method is deduced. In addition to theoretical considerations, the paper presents system simulations and measurement results of single-frequency MPPSK intergated systems, d)
