摘要
Abstract
VHF radar achieves rapid development and has wide applications in recent years because its frequency band has anti-stealth advantage and is far from the guidance frequency band of anti-radiation missile (ARM).However,there are many jamming signals in VHF band,such as radio,TV,and communications signals,which becomes a big challenge to the receiver anti-jamming design of the VHF radar.The paper in-troduces receiver anti-jamming design method based on frequency-domain multi-stage filtering technique and RF digitalized receiver sampling frequency optimization selection technique.The method can reject VHF ra-dar out-band jamming and in-band jamming effectively,and can be utilized in the design of VHF radar RF digitalized receiver.关键词
