对幂乘放大器进行了理论分析和计算机仿真。研究结果说明，对于非高斯噪声，各种形式的幂乘放大器在输入信噪比较小时，输出信噪比均有改善。这种低信噪比时所呈现的负鉴别特性，在雷达和通信中，对于小目标探测和弱信号检测具有十分重要的意义。
Abstract
Effects of the law amplifier on signal-to-noise ratio are analyzed and simu?lated in a computer. Results of analysis show that as far as non-gaussian noise is con?cerned, the output SNR of all Kinds of law amplifiers tend to improve very much so far as the input SNR is small. The characteristic of negative indentification for small input SNR is important in the detection of small objects and weak signals in radar and commu?nication systems.
