雷达信号和通信信号相加之后的幅度变化，导致饱和功率放大器的输出产生交调失真，影响一体化信号的性能。本文研究了一种基于CORDIC算法的幅相转换技术，不仅消除了功放的非线性影响，而且易于工程实现。仿真结果表明幅相转换后的信号经过功率放大器之后能恢复成原来的信号，证明了此方法的可行性。

Traditional signal integration is simple,but the amplitude is not constant after adding. The performance of integrated signal will be affected because of the distortion and intermodulations after power amplifiers. The paper mainly studies the constant amplitude conversion bases on CORDIC. The initial signal carries on constant amplitude conversion before power amplifiers so as to reduce the affection of nonlinear. The signal from the power amplifiers can be turned to initial integrated signal after processing. The simulation results show that the initial integrated signal is successfully turned into signal of constant amplitude,and the initial amplitude-varying integrated signal can be obtained after power amplifiers.Thus prove the feasibility of this method.
