一种超宽带雷达信号模拟器的设计

Design of An Ultra Wideband Radar Signal Simulator

摘要:

为满足雷达装备不断增长的保障需求,研制了一套便携式雷达装备检测系统,该检测系统的核心组成部分是超宽带雷达信号模拟器。模拟器采用低频段基带信号与高频段本振信号 2次混频来模拟产生 0.05~16 GHz范围内多种体制的雷达信号,最后完成了电路实现,经过信号测试各项指标均达到设计要求。

Abstract:

In order to meet the needs of a certain type of radar equipment increased security requirements, a set of portableradar equipment detection system was developed, the ultra wideband radar signal simulator was the core of the detectionsystem. The baseband signal of low frequency was mixed with the vibration signal of high frequency band twice to generatemany kinds of radar signal simulation system in the range of 0.05~16GHz in the simulator. Finally, the circuit implementa.tion was completed. After signal test, the indicators of radar signal simulator reached the design requirements.
