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. The device comprises a foam cabin. A foam ball is arranged in the foam cabin. The internal portion of the foam ball is used for setting chaff. The two opposite panels of the foam cabin are provided with ventilation holes which are uniformly distributed. A blower air channel or an air-intake air channel used for floating the foam ball in the foam cabin is arranged at one panel which is provided with the ventilation holes. In the technical scheme, the chaff is arranged in chaff balls and the chaff balls are arranged in the foam cabin. Aftera draught fan is started, the chaff balls are blown to be uniformly distributed in the foam cabin. And a real chaff cloud distribution condition can be simulated. A chaff cloud characteristic test ina microwave dark room can be realized, and conditions that the chaff balls can not fly into the dark room through the hole of a cabin bottom or a cabin top and the microwave dark room is polluted areavoided.

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...
