Search Route Planning Of Anti-Radiation UAV Based On Seeker Field Of View Constraint

The search route of the anti-radiation UAV(Unmanned Aerial Vehicle)is a closed flight path that flies back and forth over the attack area when the UAV searches for the target radar radiation source.In order to solve the problem of search route planning for anti-radiation UAVs,the paper takes the characteristics of the field of view constraint of the UAV seeker as the entry point,and mainly carries out the following three aspects:(1)Construction of seeker field of view model.Based on the conversion of the body coordinate system and the ground coordinate system,a model of the seeker’s field of view is constructed on the basis of studying the overlapping effect of the potential field and the mechanical field of view of the anti-radiation UAV seeker,which provides an effective method for dynamic simulation of seeker’s searching and intercepting target radar signals.(2)Anti-radiation UAV search route planning."View coverage" established by the evaluation index of search route planning,the improved artificial potential field method for anti-radiation UAV search route planning is used,which provides a guiding significance for auxiliary decision-making of anti-radiation UAV mission planning.The improved artificial potential field method solves the unreachable objective problem of the traditional artificial potential field method by modifying the repulsion potential field function,and overcomes the randomness of artificial selection of potential field function parameters by introducing genetic algorithm to optimize the potential field function parameters.(3)Anti-radiation UAV collaborative search route planning.Firstly,the "seeker field of continuous coverage area" is defined and calculated,and then the collaborative search route is planned in the area.Finally,multiple anti-radiation UAVs for radar target "full-time field of view coverage" are realized by formulating appropriate collaborative search strategies and using first order consistency algorithm.which provides a decision-making approach for efficient implementation of multi-UAV collaborative search route planning for anti-radiation UAV.
