Technical field
The present invention relates to infrared simulator.More specifically, relate to a kind of infrared target and interference simulation device.
Background technology
The manufacture claim semi-matter simulating system of modern infrared guidance system is when providing target simulator, the emulation of interference is provided, target and interference simulation system mainly contained two kinds in the past: the first is ground target and interference simulation system+motion mode, be that target jamming all generates on ground and synthesizes, by being arranged on the polylith reflective mirror on motion, simulated scenario is reflexed to target seeker entrance pupil, or the projection system focal plane that adopts image bundle that target jamming scene is reached on five axle turntable housings is projected to guided weapon entrance pupil again.The common floor space of this mode is large, research fund is high. and the second way is that target and interference simulation system are directly installed on five axle turntables, as shown in the optical system principle schematic of infrared target in Fig. 1 prior art and interference simulation device, this optical system comprises black matrix 1 ', optical filter 2 ', field stop 3 ', the first spectroscope 4 ', optical gate 5 ', the first speculum 6 ', attenuator group 7 ', the second speculum 8 ', the second spectroscope 9 ' and projection objective group 10 '; 1 '-2 '-3 '-4 ' – 5 '-6 '-9 '-10 ' is for disturbing light path, and 1 '-2 '-3 '-4 '-7 '-8 '-9 '-10 ' is target light path.This scheme is used a scene generation system, uses a set of black matrix light source and field stop mechanism, directly isolates interference light path by the first spectroscope from target light path, adds energy attenuation mechanism in target light path.Jamming bomb disengaging movement realizes by the swing of speculum 6 '.Target light path and disturb light path finally by reflective second spectroscope, two-beam is compound, through the 10 ' projection of projection objective group to missile homer.
But such scheme has following defect:
(1) target and interference, with same black matrix and diaphragm, can not control separately the size and shape of target and interference, more can not control the rotation of target.
(2) in system, used two spectroscopes 4 ' and 9 ', system energy loss is doubled.
Summary of the invention
The technical problem to be solved in the present invention is in the situation that lab space is limited, a kind of infrared target and interference simulation device are provided, the infrared target of this simulator and the power of interference and size shape are all variable separately, target can rotate in visual field, and interference can be done two dimensional motion in visual field.Infrared and interference simulation device can meet the requirement that is arranged on the volume and weight on five axle turntables.For solving the problems of the technologies described above, the present invention adopts following technical proposals:
