为提高雷达的战术和技术性能,数字计算技术在雷达中得到了广泛的应用。数字技术具有许多优点,例如线性好、大动态范围、零漂小、抗干扰好、使用灵活等,所以数字电路代替了许多模拟电路。快速电子计算机具有强大的信息处理能力和高精度的实时控制能力。在人类大力开发宇宙空间的时代,出现了可以观测数千万公里的深空雷达。雷达目标的运动速度已由300公尺/秒提高到第二及第三宇宙速度或更高(天体)。在军用雷达方面有更高、更严格的要求。导弹和卫星防御雷达应有高分辨力、多目标、多功能、多信息、实时控制及快速处理的能力。在这些雷达系统中,计算机成为信息处理、实时
To improve the tactical and technical performance of radar, digital computing technology has been widely used in radar. Digital technology has many advantages, such as good linearity, large dynamic range, zero drift, good anti-jamming, flexible use, etc., so digital circuits instead of many analog circuits. Fast computer with powerful information processing capabilities and high-precision real-time control. In an age when mankind vigorously developed space, a deep space radar capable of observing tens of millions of kilometers appeared. The radar target’s movement speed has been raised from 300 m / s to the second and third cosmic speeds or higher (celestial bodies). There are higher and more stringent requirements for military radars. Missiles and satellite defense radars should be capable of high resolution, multi-target, multi-function, multi-information, real-time control and rapid processing. In these radar systems, computers become information-processing, real-time
