摘要
介绍了法国 LP23K航管雷达接收机五个关键模块的国产化改造设计。经过改造设计的国产化接收机各项性能指标如噪声系数、系统增益、动态范围、激励功率等均超过原接收机的指标。使用证明,能完全代替原进口模块。
This paper introduces improvement and design of the five key modules of the French LP23K radar receiver. After reconstruction,the new receiver excels the old one in the performance indexes,such as noise factor, systern gain,dynamic range,source power and so on. By application,it is proved that the new receiver can replace the old completely.
