This paper presents a multiple routes planning algorithm based on particle swarm algorithm (PSO) and hierarchical clustering to overcome the problem of the sensitivity of k-means clustering to the initial clustering center. Firstly, numerous feasible routes are initialed by PSO. Secondly, the model of multiple routes planning based on hierarchical clustering algorithm is designed and the hierarchical...
As a strategic deterrent force attack, airborne laser weapon represents the development direction of future weapons. The various factors influencing the airborne laser weapon combat effectiveness are analyzed. The models of airborne laser weapon shot error rule and target coordinate kill rule are established. Then the sp ecific a irborne laser weapon kill p robability model is established. A target...
A Battle Damage Assessment (BDA) algorithm with change detection of Synthetic Aperture Radar (SAR) images is established. Aiming at the difficulty of accurately distinguishing the attacked and non-attacked areas within a large swath SAR scene, SAR images are divided into small patches, and Scale Invariant Feature Transform (SIFT) semantic features are extracted for each of them. According to the semantic...
The task of on-line planning paths for unmanned aerial vehicle (UAVs) across a 3D terrain has been paid considerable attention in academia. This paper presents a new tactical path planning algorithm, called List Expanding Algorithm (LEA), which aims at generating a safe path from initial position to destination without any collision with forbidden regions such as threats and obstacles. The input of...
To solve the question that the UCAV independent flight, a kind of layered fight control arithmetic, based on discrete variable structure control, is brought out. The arithmetic uses a kind of guidance law bring the contrail which should be flight. The guidance law is based on variable structure control and restrict by enter angle. And then make discrete mode on airplane and trace point, compute the...
In the air-to-ground multi-target combat, the target attack order is of great importance to the efficient assignment of weapon resources. In accordance with the characteristics of multiple attribute decision and the threat assessment, a model for assessing targets' threat degree in air-to-ground multi-target attack is established based on the theory of fuzzy multiple attribute decision. The targets'...
