Problems solved by technology

At present, most of the existing dynamic infrared target simulators use DMD or resistance array to simulate infrared scenes. These two methods can well realize infrared target modeling and simulation, but the two systems are complex and expensive, and are usually used in fixed experiments. The small dynamic infrared target simulator involved in this article is small in size and easy to move. It can be tested independently or with a multi-axis turntable for simulation testing.

Embodiment

[0025] For the use of specific occasions, it is necessary to provide a series of infrared targets of specific shapes for the infrared camera, and install targets of different shapes according to different needs. , switch between different targets through the electric target wheel.

[0026] Infrared target simulator

[0027] It is necessary to design specific targets, motorized target wheels, black bodies, and infrared optical collimation systems, such as figure 1 shown.

[0028] target. The target is a metal target plate, which is hollowed out into a specific shape. The temperature of the target plate body is the ambient temperature, and the temperature of the hollowed out part is the black body temperature, which is the simulated infrared target.

[0029] Motorized target wheel. The switching of the target needs to be completed by the electric target wheel. The electric target wheel is equipped with 12 targets, and the stepping motor is used to drive the target wheel to r...

Abstract

The invention belongs to the field of infrared guide head testing, and particularly relates to a minitype infrared target simulation device capable of achieving miniaturization of infrared target simulators and simulation of certain infrared targets. The minitype infrared target simulation device comprises an optical collimation system, an electric target and a blackbody. The optical collimation system comprises a lens cone (1), a lens installing assembly (2), a lens cover (3), a secondary lens installing assembly (4), an electric target wheel (5), a connecting plate (6), an off-axis parabolic reflector (7) and a plane reflector (8). The lens installing assembly (2) is arranged on the left side of the interior of the lens cone (1). The lens cover (3) is arranged on the left side of the lens installing assembly (2). The off-axis parabolic reflector is arranged on the right side of the lens installing assembly. The secondary lens installing assembly is arranged on the right side wall of the lens cone. The plane reflector is installed on the secondary lens installing assembly. The connecting plate is arranged on the lens body of the lens cone. The electric target wheel is arranged above the plane reflector and the outer side of the lens cone wall. The blackbody is arranged above the electric target wheel.

Description

technical field [0001] The invention belongs to the field of infrared seeker testing, and in particular relates to a small infrared target simulation device. Background technique [0002] The infrared target simulator is an important part of the infrared guidance simulation. The infrared target simulator is used to simulate the movable and energy-adjustable target source to test the missile system's sensitivity, capture probability, modulation characteristics, tracking accuracy and other indicators. The accuracy and stability of the infrared target simulator are directly related to the main technical indicators and performance of the missile system, so it is of great significance to develop the corresponding target simulator in a targeted manner. At present, most of the existing dynamic infrared target simulators use DMD or resistance array to simulate infrared scenes. These two methods can well realize infrared target modeling and simulation, but the two systems are complex...
