Abstract

The invention relates to an intelligent detector of an anti-interference performance of a pulse laser range finder and a detection method of the anti-interference performance. The intelligent detector comprises a collimation optical system, a photovoltaic conversion and processing circuit, a main control circuit, a light source driving circuit, a combined simulative light source and a human-computer interaction interface. According to the intelligent detector and the detection method disclosed by the invention, a simulative range and the delaying time corresponding to the computation of the main control circuit are set through the human-computer interaction interface; simulative range finding echoes and interference echoes are sent by controlling the combined simulative light source; and emission powers and emission moments of the interference echoes are gradually adjusted so that a simulative detection of the anti-interference performance of the pulse laser range finder is realized. According to the intelligent detector and the detection method disclosed by the invention, a working mode that an existing detection only can detect outdoors in a long distance is changed and the detection of the anti-interference performance of the pulse laser range finder can be carried out indoors, so that a utilization field is more flexible and the detection is more convenient; and interference factors of weathers and environments in the detection work are reduced and a detection result is more accurate.

Description

technical field [0001] The invention relates to a performance detection device of a pulsed laser ranging machine, in particular to an intelligent detector for the anti-interference performance of a pulsed laser ranging machine and a detection method for the anti-interference performance. Background technique [0002] The laser rangefinder is by far the most armed military laser equipment. A large number of laser rangefinders are equipped on the weapon platforms of many countries, such as tanks, armored vehicles, surface ships and various fighter jets. These laser rangefinders are an essential part of the fire control system, so a lot of research has been done on the interference methods of laser rangefinders at home and abroad. [0003] At present, the detection of the anti-jamming performance of the 1.06μm pulsed laser rangefinder generally adopts the outdoor method, using high-power laser jamming equipment to transmit high-frequency pulse encoded information over a long d...
