为实现引进装备高频接收机混频前置中频放大器组合的国产化功能替换,提出了一种基于逆向工程方法和信号处理技术的新思路。通过剖析原混频前中组合的组成、工作原理及性能指标,对其进行反设计。目前,国产化混频前中组合已用于装备的维护保障,能够满足引进装备的正常使用要求。
In order to replace the domestic-made function of the pre-IF amplifier with high-frequency receiver and mixer, a new idea based on reverse engineering and signal processing technology is proposed. Through the analysis of the composition of the original mix before the composition, working principle and performance indicators, its anti-design. At present, the domestically produced mixing front combination has been used for equipment maintenance and protection, which can meet the normal use requirements of imported equipment.
