雷达信号产生的小程序 对初学者比较有用 用软件自带的函数实现(Applet radar signal produced more useful for beginners comes with software functions to achieve)

matlab源程序，通过拉普拉斯变换进行两幅图像的融合，融合效果好(matlab source, through the Laplace transform fusion of the two images, good fusion effect)

test simulation channel power

说明：  关于j2me的midlet事例源码, 能帮助你晋级!(J2ME on the vulnerabilities example source code, can help you cut!)

This problem is main to solve a PDE. And we have validate hte program with the analysis results.

RADAR scateriing using pulse compression principle

说明：  本程序实现了短数据序列不同窗函数的welch功率谱估计，然后又求了他们的平均标准差，从而判断各个窗函数的优劣。只要稍作修改就能实现不同信噪比下的功率估计，同时也可以实现长数据序列的估计。(This procedure has a short data series of different welch window function power spectrum estimation, and then seek their average standard deviation, and thus to determine the merits and demerits of each window function. As long as we can with some slight modifications under different signal to noise ratio power estimate, but also the realization of a long data sequence can be estimated.)

设计一个采用 2ASK（OOK）调制的数字通信系统，给定载波频率为码元速率的2倍，产生二进制随机数据，并仿真其对应的 2ASK 调制波形，分析其频谱。所产生的调制波形加入不同信噪比的白噪声，再观察其波形和频谱变化。(Design of a use 2ASK (OOK) modulated digital communication system, a given carrier frequency is twice the symbol rate, to generate a random binary data, and simulate its corresponding 2ASK modulation waveform, the spectrum analysis. Modulated waveform generated by white noise with different noise ratio, and then observe its waveform and spectrum changes.)

refprop是一款用matlab调用的制冷剂物性查询软件，这里用matlab调用。( refprop is the refrigerant physical properties of the query software, a call using matlab using matlab call. )
