摘要
针对双波束天波雷达工作中波束宽度与发射资源之间的矛盾,根据发射波束的扫描原理、常见的发射通道规划方法及雷达双波束扫描的实现方法,从工作频率、波束指向和发射机数量3个方面分析了影响发射波束宽度的因素;然后设置任务场景,给出了基于波束宽度的频率选择方法;最后设置模拟场景,对比不同频率对雷达作战效能的影响,验证了该方法的可行性.
Aiming at the contradiction between beam width and transmitting resources in the work of dual-beam sky-wave over-the-horizon radar(OTHR),this paper accords to the scanning principle of the transmission beam,the common transmission channel planning type and the realization method of radar dual-beam scanning to analyze the factors affecting the transmitting beam width from three aspects:working frequency,beam direction and the number of transmitters,and then sets up the mission scenario,presenting the frequency selection method based on beam width.Finally,the paper sets a simulation scenario to compare the effects of different frequencies on radar combat effectiveness.The feasibility of the proposed method has also been verified.
