Abstract

The invention discloses a laser terminal guidance aircraft information point-to-point transmission system and method. According to the laser terminal guidance aircraft information point-to-point transmission system, a command synchronizer and an execution synchronizer are introduced to solve the problems of aircraft emission delay and laser irradiator starting delay and asynchronization; a timing module is introduced to reduce the time for guiding laser to irradiate a target, d a laser frequency encoder is introduced to encrypt the guiding laser, so that the possibility that the guiding laser is found, interfered and shielded by the target is reduced, the laser guiding process is ensured to be carried out stably and orderly, and the safety of an observation unit and the accuracy of an aircraft are improved; and a communication controller is introduced, so that the frequency of ultra-short wave communication is adaptively changed along with the change of a channel, and the stable and optimal communication quality is always ensured.

Description

Technical field [0001] The present invention relates to the field of guidance control of laser guidance aircraft, and in particular to a laser-derived aircraft information point pair point transmission system and method. Background technique [0002] The laser guidance aircraft is an increasingly widely widened magic aircraft. The basic working principle of the laser guidance aircraft is: laser illuminating target, laser detectors, in real time, laser detectors in real time, in real time to detect target diffuse laser signals in real time; After entering the field of detector, the laser detector can control the corresponding pulse engine or servo according to the deviation signal of the field of view, and correct the flight trajectory of the aircraft, thereby increasing the intensity accuracy, and basically ensures the position of the aircraft in the laser. Landing. [0003] The workflow of the traditional aircraft information transmission system is: the front viewer searches for...

Problems solved by technology

[0004] The disadvantages of the traditional information transmission system are as follows: 1) The traditional information transmission is carried out through the radio station. Because of the low degree of automation, there is a delay in information transmission caused by manual sending and receiving commands. The aircraft may not be able to accurately hit the target; 2) The laser irradiator is turned on at the same time as the aircraft is launched. The laser irradiation time is longer, and the frequency of the guided laser is fixed, making it easier for the target to detect the guided laser and take measures such as escaping, jamming, and shielding. It reduces the accuracy of the aircraft, and also increases the possibility of exposure of observers in front; 3) The ultrashort wave station has no adaptive frequency selection function, and the ultrashort wave channel has defects, that is, the transmission quality of the ultrashort wave channel is unstable, and the transmission of a single channel leads to communication The quality fluctuates greatly, coupled with the impact of noise interference on communication, the effect of information transmission is difficult to guarantee; 4) It takes a long time for the commander to analyze and evaluate the damage information of the target, which may lead to target transfer or concealment, and subsequent launch of the aircraft is also difficult to achieve. expected result
