Abstract

A multi-band target / background generating device comprises a multi-band composite optical system, a multi-band target black body, a multi-band background black body, a target assembly and a two-dimensional posture adjustment platform. The multi-band composite optical system is composed of a plane mirror and an off-axis paraboloid mirror. The target assembly is composed of a target base and a target, wherein the target is arranged on a focal plane of the off-axis paraboloid mirror. The multi-band target black body is arranged behind the target and irradiates a target hole to form a target light beam. A radiation light beam emitted by the multi-band background black body irradiates the inner surface of the target to form a background light beam. After the background light beam and the target light beam are combined into one beam, the beam is emitted from the target, reflected to the off-axis paraboloid mirror through the plane mirror, and straightened into parallel light beams through the off-axis paraboloid mirror so as to form an infinite multi-band target / background which is used for a test of equipment to be tested. The multi-band target / background generating device can provide the infinite multi-band target / background for an infrared seeker so as to detect the performance of a system of the infrared seeker.

Description

technical field [0001] The invention belongs to the field of infrared seeker system testing and relates to a multi-band target / background generation device. Background technique [0002] Existing target simulators or collimators can only provide infinitely distant multi-band targets for the optical seeker, which can be used for testing equipment under test. However, precision-guided weapons work in a complex environment. In addition to the variable target radiation characteristics, the background temperature in the field of view of the seeker also changes. Different background temperatures have different radiation characteristics, which seriously affect the detection performance of the seeker system. Therefore, it is of great significance to develop a seeker test device that can simultaneously generate multi-band targets and backgrounds. Contents of the invention [0003] The purpose of the present invention is to provide a multi-band target / background generating device, ...
