直升机低空突防中威胁因素的作用距离

分析了武装直升机在实施低空突防时的主要威胁来源.通过对雷达探测原理和低空条件下雷达受到的限制分析及其威胁作用距离计算,阐明了低空探测时常规雷达的不足,介绍了目前新的低空电磁探测方式;通过红外探测、噪声探测的原理和特点研究,表明了这两种方式在直升机低空突防威胁中的重要性,计算了其作用距离;讨论了上述三种方式作用距离,计算结果可以为航迹规划中参考轨迹和安全走廊的确定提供了参考.

Range Research of Threats to Helicopter in the Low Altitude Penetrantion

The main threat resources to attack helicopter in the low altitude penetration were analyzed in the paper.By the analysis of theory of radar detection and limition to the radar in the low altitude and the threat range,the deficiency of the conventional radar in the detection of the low altitude was illuminated.The new methods of the electromagnetism detection were introduced.By the research of the infrared detection and noise detection,the significance of the two methods were indicated,and the threat ranges of these detections were figured out.The calculated threat ranges were discussed in the end.Which can be taken as the reference of reference path and safe corridor in route planning.
