摘要
红外探测距离作为红外搜索跟踪系统(IRST)的重要技术指标,如何便捷地对红外探测距离进行精确测试成为影响红外搜索跟踪系统(IRST)研制的关键环节。分析了现有的红外探测距离测试的外场试飞存在的优缺点,提出了红外探测距离的缩比探测方法。该方法利用缩比探测的原理,引入真实大气路径和真实场景,通过精确控制模拟辐射源的辐射能量来实现红外搜索跟踪系统(IRST)红外探测距离测量,针对近地面大气透过率复杂多变的特点,引入了大气透过率校正因子对近地面大气透过率进行校正,经过A,B两型红外搜索跟踪系统(IRST)的试验验证,测得的红外探测距离与真实试飞数据最大误差为12%,且相对于外场试飞,极大地缩短了研制周期,降低了研制费用。
The infrared detection range is an important indicator of the Infrared Searching and Tracking( IRST) system. How to quickly and accurately measure the infrared detection range has become a key part of IRST development. This paper analyzes the advantages and disadvantages of the current measuring method in the flight test and proposes a new method to test the infrared detection range. This method uses the principle of contraction detection to introduce the real atmospheric path and real infrared scenes. The measurement of the infrared detection range is realized by accurately controlling the energy from a simulated radiating source. In view of the complicated and variable atmospheric transmittance near the ground the correction factor of atmospheric transmittance is introduced to calibrate the atmospheric transmittance near the ground.Tests for two IRST systems of Type A and Type B were carried out. The maximum error between the measured infrared detection range and the flight test data was 12%. Compared with flight tests,this method greatly shortens the development cycle and reduces the development costs.
