In the unmanned photoelectric reconnaissance vehicle network, each node cooperates to locate the target, which is beneficial to expand the reconnaissance range and obtain the target position information covertly. The unmanned photoelectric reconnaissance vehicle of each node can provide the angle information relative to the target when it reconnoitres the target. How to use the angle information of the target detected by each node to obtain the estimation of the target position information is worth studying. This paper studies the passive positioning technology in the unmanned photoelectric reconnaissance vehicle network, establishes the model of the unmanned photoelectric reconnaissance vehicle network for cooperative target positioning, and uses the least-squares method to design the target positioning algorithm. The error between the target position value and the true value is within 10m, which proves that the algorithm can effectively obtain the target position information, and provides an effective method for the hidden acquisition of target position information in the unmanned photoelectric reconnaissance vehicle network.
The vibration environment of the internal opto-machinal system of the electro-optical pod is different from the external vibration environment and needs to be accurately defined. Based on the detailed analysis of the vibration source distribution and response bandwidth of the airborne electro-optical system, the Cassegrain Opto-mechanical System is taken as the research object, and the complete analysis process is established from the original environmental excitation. The equivalent vibration algorithm is used to determine the micro-vibration conditions. The finite element detail model of the connection method is used for dynamic response. At the same time, based on the simulation model optomechanical system, an optical axis drift analysis method based on feature point correlation and response extremum judgment is proposed. The relationship between the displacement mode and the amount of drift of the optical axis is obtained.
