Abstract

The invention belongs to the technical field of airplane outfield maintenance guarantee, and relates to a portable radar signal simulator. The radar signal simulator comprises an antenna module, a frequency synthesizer module, a display control module and a power supply module which are installed in a shell. The frequency synthesizer module is integrated with a 2GHz-18GHz functional module and a 18GHz-40GHz functional module, and an analog signal output interface is reserved; the antenna module is integrated with a slot antenna and an antenna horn body, receives the radar analog signals outputby the frequency synthesizer module, and transmits 2GHz-18GHz analog signals and 18GHz-40GHz analog signals through the slot antenna and the antenna horn body respectively; the display control modulecompletes radar signal parameter setting and working state display; the problem that a radar signal simulator is large in size, heavy in weight and inconvenient to carry for field guarantee is solved, and the maintenance efficiency of army support personnel is improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft outfield maintenance support and relates to a portable radar signal simulator. Background technique [0002] At present, in the field of domestic helicopters, a two-level (army-level and base-level) maintenance system and three maintenance methods (scheduled, condition-based and status monitoring) are used for design: [0003] Troop-level maintenance: that is, at the site where the equipment is used, the ground crew or the support personnel using the troop use the BIT or field support equipment to perform fault detection, isolation, and maintenance repairs, mainly by replacing the LRU. [0004] Base-level maintenance: return the faulty LRU to the repair shop of the army or the contracting unit for repair, and use all means such as relatively complete repair facilities and support equipment to detect, isolate, and repair the faulty LRU. [0005] The radar signal simulator of the guarantee equipme...
