发射多波束的非线性功放影响分析
The Analysis to the Effect of Nonlinear Power Amplifier on Transmitting Multibeam
摘要
Abstract
With increasingly diverse and complex requirements on radar system,the application of mul-tifunction phased array radar has become a trend,and multi-beam technique is exactly one of the main tech-niques.For the transmitting system,one of the difficulties of the realization of transmitting multi-beam is that a nonlinear power amplifier(PA)will affect the formation of multi-beam.Therefore,we analyze the effect of nonlinear PA on the transmitting multi-beam.We study the source of power amplifier non-linear effects and simulate the effect of nonlinear PA on the beam pattern and the signal-to-interference power ratio, which provides an evidence of design PA in practical engineering.关键词
