普通脉冲雷达由于存在地物杂波干扰不能探测到低空飞行的飞机,多普勒雷达由此应运而生.雷锡恩公司首次研制了连续波多普勒雷达,并将之应用于“麻雀”和“霍克”导弹中.以后人们又研制了脉冲多普勒雷达,它兼有脉冲雷达和连续波雷达的特性.介绍雷锡恩公司研制连续波雷达中的关键技术,叙述防空问题的特殊观点.详细论述低空防空武器制导系统的基本技术问题(主要有指令、噪声和尖叫声等)和解决这些问题的主要途径.最后介绍低空防空导弹技术和雷达技术的进展以及现状.
Doppler radar came into being due to the inability of ground-level clutter to detect low-altitude aircraft in ordinary pulse radar, Raytheon developed the continuous wave Doppler radar for the first time and applied it to the “Sparrows” and In the “Hawk” missile, people later developed pulse Doppler radar, which combines the characteristics of pulsed radar and continuous wave radar.It introduces Raytheon’s key technology in developing continuous wave radar and describes the special viewpoint of air defense Describe in detail the basic technical issues (mainly instructions, noise, screams, etc.) and the main ways to solve these problems in SLW guidance systems. Finally, we introduce the progress and current status of LSTAR and radar technologies.
