The experimental study about laser-induced dizziness effect of medium-wave infrared seeker which based on image processing

摘要

In view of the problem of laser dizzy interference of medium-wave infrared seeker detector in the field of photoelectric confrontation, there is a lack of equidistant distance test to verify the problem. In this paper, a medium-wave infrared seeker for short-range precision guided missile CCD detector was used as the subject, and the 3.8 mu m wavelength medium wave laser was used as the laser source to study the calibration of the laser. In the experiment, two locations with a viewing distance of 14.5 km were selected to place the laser and missile seeker detectors respectively. The atmospheric transmittance was estimated using the MODTRAN software based on the meteorological parameters provided by the simple meteorological monitoring tool. Under the different target power density conditions, the simulation of the missile seeker head of the interference of the dizzy effect. By analyzing the interference images in the tracking state, the corresponding qualitative and quantitative dizziness interference results are obtained. After the calculation and analysis, it is considered that the laser energy output from the mid wave infrared laser is 0.08 mW/m(2) when the power density of the target surface of the detector is 0.08 mW/m(2), respectively, under medium meteorological conditions with a visibility of 0.625. Box cannot lock the original target, there cannot effectively extract the target dizzy effect. The experimental results show that the anti-jamming ability of the anti-jamming capability of the medium-wave infrared precision guidance probe is verified by the photoelectric countermeasure, and it is considered that the dodge power density is smaller when the interference laser wavelength matches the wavelength of the seeker detector. The experimental data can provide theoretical guidance for the inversion and determination of parameters in the study of the medium wave infrared photoelectric countermeasure.
