本发明的背景1.本发明的范围脉冲多卜勒设备通常用在动目标显示雷达系统的雷达频率的前端。用常规的方法进行脉冲传输时,该设备可获得距离分辨率。多卜勒原理(目标相位信息)用来把动目标从地物背景中分离出来。为了充分地利用发射机的平均功率,最理想是雷达工作时具有最大可能的占空比(开关比),使用这种方法使发射机的费用降低。对短距离的超高频雷达(几英里范围内)来说,最大占空比也通常使用固态结构,特别是在可靠性和尺寸上提供一个最理想的改进方法。然而,对普通的脉冲多卜勒雷达来说,占空比高,使距离响应模糊,故对其分辨率需进行专门处理,或者距离分辨率低,使雷达失效。
BACKGROUND OF THE INVENTION 1. The range pulsed Doppler apparatus of the present invention is generally used at the front end of a radar frequency of a moving target display radar system. When using conventional methods for pulse transmission, the device achieves distance resolution. The Doppler principle (target phase information) is used to separate the moving target from its background. In order to make full use of the average power of the transmitter, it is desirable to have the maximum possible duty cycle (switching ratio) for the operation of the radar, using this method to reduce the cost of the transmitter. For short-range UHF radars (over a few miles), the maximum duty cycle is also often used in solid-state structures, especially in terms of reliability and size to provide an ideal improvement. However, for normal pulsed Doppler radars, the duty cycle is high, obscuring the range response, so the resolution needs to be specifically addressed or the range resolution is low, rendering the radar ineffective.
