Problems solved by technology

Infrared surface source decoy is a new type of infrared interference, but in the prior art, the influence of the medium-wave and long-wave reflected environmental radiation of the aeroengine on the measurement results is not considered in the radiation characteristic test process of the infrared surface source decoy. Not high, big error

Embodiment Construction

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as Figure 1-2 As shown, the test method for the combined radiation characteristics of an aero-engine and a foil-type infrared surface source decoy includes the following steps:

[0032] Step 1: Set the working state of the aeroengine, the working state is the exhaust temperature of the aeroengine, and the exhaust temperature includes 770K and 970K;

[0033] Step 2: Set the launch state of the decoy bomb, which is launched statically from the ground, and the launch state is initial velocity and pitch angle...

Abstract

The invention discloses an aero-engine and foil type infrared surface source bait combined radiation characteristic test method, and relates to the technical field of infrared radiation characteristic test. The method comprises the following steps: a working state of an aero-engine and a launching state of a decoy projectile are set; after the test is started, proper measurement distances are selected according to different bait states, and infrared image sequences and infrared radiation intensities of the surface source infrared bait and the aero-engine in medium-wave infrared and long-wave infrared bands are tested through infrared test equipment; according to the invention, the aero-engine and the surface source bait are taken as test targets, different working states are set for the aero-engine, different emission states are set for the surface source bait, and medium-wave and long-wave infrared radiation image sequences and infrared radiation intensity of the combination of the surface source infrared bait and the aero-engine are obtained through testing from different test angles; and meanwhile, proper measurement distances are selected according to different bait states, so that the test result is more accurate and comprehensive.

Description

technical field [0001] The invention relates to the technical field of infrared radiation characteristic testing, in particular to a method for testing the combined radiation characteristic of an aero-engine and a foil-type infrared surface source decoy. Background technique [0002] With the continuous development of new infrared detection and infrared guidance technology, especially with the application of infrared imaging technology and spectral recognition technology, the survival of military targets in modern battlefields has become particularly severe. The passive jamming technology that the profiling decoy acts as a false target to interfere with the enemy's detection and guidance has been paid more and more attention by various countries; [0003] Infrared radiation intensity is an important parameter to describe the thermal radiation characteristics of objects, and it is of great value in the fields of aerospace, industrial and agricultural production, and national ...
