Abstract

The high intensity dynamic infrared stimulator is placed in the field and projects a time dependent infrared beam toward the flying aircraft.The time dependent high intensity of the beam simulates the infrared emittance of an approaching missile in the 3to 5micron spectral range as sensed by a Missile Warning Systems.It is able to test the ability of the MWS to detect the threat and recognize in-flight.It is composed of two strong IR sources in the focus of a large reflective optics.The projected intensities are controlled by two motor driven sets of parallel slats,positioned in front of the optics,in the manner of a venetian blind.The intensity of the beam and the uniformity of the beam are measured.Experimental result show that the intensity of the beam is higher that 840W/sr,the uniformity of the beam is 89%,design scheme fully meet the design requirements.

高强度动态红外威胁刺激器的研究

高强度动态红外刺激器放置在现场，并向飞行的飞行器发射随时间变化的红外光束。光束的时间依赖性高强度模拟了导弹预警系统感知的接近导弹在3到5微米光谱范围内的红外发射。它能够测试MWS探测威胁和识别飞行中的能力。它是由两个强红外光源集中在一个大型反射光学系统上。投射的强度由两个电机驱动的平行板条组控制，它们位于光学元件的前面，以百叶窗的方式。测量了光束的强度和光束的均匀性。实验结果表明，光束强度高于840W/sr，光束均匀度达到89%，设计方案完全满足设计要求。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
