Embodiment Construction

[0026] The invention provides a chaff cloud simulation device, which is used to solve the problem that the chaff interference resistance ability cannot be quantified because the physical size of the chaff is too small.

[0027] To achieve the above object, the technical solution provided by the invention is:

[0028] A chaff cloud simulation device, comprising a foam cabin, in which foam balls are arranged, and the foam balls are used for setting chaff;

[0029] Two of the opposite panels of the foam cabin are respectively provided with uniformly distributed ventilation holes, and one of the panels provided with the ventilation holes is provided with an air blowing channel or suction for making the foam balls float in the foam cabin. air duct.

[0030] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] This embodiment provides a chaff cloud simulation device, which is used for chaff interference of air...

Abstract

The invention provides a chaff cloud simulation device, which comprises a foam cabin, in which foam balls are arranged, and the foam balls are used for setting chaff; two of the opposite panels of the foam cabin are respectively provided with evenly distributed ventilation holes, An air blowing air channel or an air suction air channel for making the foam balls float in the foam cabin is arranged at one of the panels provided with the ventilation holes. In the technical solution provided by the present invention, the chaff is arranged in the chaff ball, and the chaff ball is arranged in the foam cabin. When the fan is turned on, the chaff ball is evenly distributed in the foam cabin, and the chaff cloud can be simulated. the real distribution. The technical scheme provided by the invention can realize the chaff cloud characteristic test in the microwave anechoic chamber, and will not cause the chaff balls to fly into the anechoic chamber from the hole in the bottom or the top of the cabin and cause pollution to the microwave anechoic chamber.

Description

technical field [0001] The invention belongs to the technical field of radar target simulation equipment, and in particular relates to a chaff cloud simulation device. Background technique [0002] As an important passive jamming equipment, airborne chaff jamming is mainly used for airborne self-defense. It is one of the most effective means for combat aircraft to deal with radar-guided missiles, and it plays a very important role in protecting airborne aircraft from missile attacks. The principle of airborne chaff jamming radar is mainly "centroid jamming". The theoretical basis is that the spatial tracking point of the radar is located on the energy center in its resolution unit. When there is one target in the radar resolution unit, the radar tracks the scattered energy center of the target; when there are two targets in the radar resolution unit, the radar tracks the energy center formed by the two targets, which is usually called is the "centroid". When the aircraft i...
