Description: 程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制；
根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声；
接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。
结果表明10^-3对应大约12->13dB-Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB

Description: 提供一个cell-weraging constant false alarm rate (CA-CFAR)的算法，基于信号检测的方法。-We present a method for evaluating the performance of
cell-weraging constant false alarm rate (CA-CFAR) processors
which use the anplitude of echo signals rather than their
squared amplitude Results are presented for the case of Rayleigh
clutler/mise statistics for which some sirnulatiom have been
reported recently by other authors [:I. Detection probabilities are
evaluated for the case of a Rayleigh fluctuating target embedded
in Rayleigh clutter/noise for linear-law CA-CFAR processors.
These results are observed to be practically identical to those of
square-law CA-CFAR processors for which analytical expressions
are readily available. We also verify these observations using
Monte Carlo simulations. The same conelusion is reached in the
case of a nonfluctuating target embedded in Rayleigh clutter/noise
for which only simulation results are presented here.
