A Design of Counter Reconnaissance Based on Subsection LFM Modulation Random Waveform
摘要
Abstract
Generally,in modern radar system,many methods are used to reduce its intercepted proba-bility and enhance its secluded performance.This is the main purpose of modern radar to enhance its counter reconnaissance performance.The performance of counter reconnaissance is mainly reflected in the waveform design.LPI signals are often used to achieve the effect,but some ordinary LPI signals are regular and famil-iar to normal reconnaissance receiver.Combining the random characteristics of noise with the pulse compres-sion performance of LPI signal,a subsection LFM modulation pulse technology based on the random wave-form is proposed,which makes the waveform of pulse have the character of noise and strong pretending effect to reduce the intercepted probability enormously.The simulation indicates that the design has a good performance.关键词
