摘要
从软件无线电的概念出法,论述了在相控阵雷达系统中采用软件无线电技术的必要性和可能性;其次详细地论述了相控阵雷达系统中软件无线电的实现形式:即天线子系统,收、发子系统,信号处理子系统。最后对软件无线电技术在现代雷达中的发展进行了展望。
The necessity and the feasibility of software radio realization in phase array radar system are discussed. Then, it is expounded in detail how the software radio structure can be implemented, which includes an antenna subsystem, receiving and transmitting subsystems, and a signal processing subsystem in phase array radar system. Finally, the developmental trend of software radio techniques in the modern radar is forecasted.
