一、前言以微波瞬时测频接收机(下面筒称IFMR)作为测频及模-数转换的频率引导设备,近年来在国外已开始应用。如1980年完成海上试验、现已装备部队的英国“施密特干扰机”就是采用这种技术的干扰设备。国内近几年也开始了这种技术的研制工作,并已取得一定成绩。实验结果说明,这种频率引导系统具有快速准确的特点,目前可用作对非频率捷变雷达实施瞄准式杂波干扰或欺骗式干扰。下面对这种频率引导系统的工作原理和实验结果分别加以说明和分析。
I. INTRODUCTION Microwave instantaneous frequency measurement receiver (hereinafter referred to as the IFMR) as the frequency measurement and frequency conversion device-to-digital conversion equipment has been applied abroad in recent years. For example, the British “Schmidt Jammer”, now equipped with troops, completed the sea trial in 1980, and was the interfering device using this technology. In recent years, China has also started the development of this technology and has achieved some success. Experimental results show that the frequency-guided system is fast and accurate and is currently used as a target for clutter-based or deception-jamming of non-frequency agile radars. The following describes the principle and experimental results of this frequency guidance system, respectively, and analysis.
