As electronic warfare has become the core element that determines the course and trend of war,in order to gain and maintain the advantage of electromagnetic space,the comprehensive perception of electromagnetic signal situation in the target area which is the height of modern information warfare has become one of the primary problems to be urgently solved in the field of national defense security and military struggle preparation.As a key technology of distributed electronic warfare,cooperative coverage can realize the fusion perception of electromagnetic signal situation and complement the blind areas,thus providing information support for subsequent battle command decisionmaking.Therefore,the research content has important military theoretical significance and application value.This paper focuses on the cooperative coverage of air-to-ground in the blind area of electromagnetic signal situational awareness under complex terrain environment.Based on the description of relevant research background and research status,the cooperative awareness technology of ground electronic warfare nodes,the cooperative cruise coverage technology of perception blind area and the cooperative complementary coverage technology of air-to-ground are studied.Firstly,to solve the problem of incomplete data acquisition in distributed ew network composed of static ground EW nodes randomly deployed in complex terrain environment,an improved CS-Kriging-BP interpolation algorithm is proposed to estimate the electromagnetic signal data in the uncovered blind area.Finally,the data collected by ew nodes and interpolated estimation data are fused to generate a complete electromagnetic signal situation map of the target area,providing information support for the next step of air-ground cooperative coverage.The simulation results show that the algorithm can restore the coverage of electromagnetic signal accurately.Secondly,in view of the electromagnetic signal generated by the situational awareness blind area in this picture,this paper puts forward a kind of fill point collaborative coverage algorithm based on ICSGWO algorithm,this algorithm by reconstructing fusion signal strength weight and weight optimization objective function,the realization of airborne ew node deployment location optimization,achieve the purpose of the fill point space together to cover.The simulation results show that this algorithm has better performance and higher comprehensive coverage income,and can implement air-space cooperative coverage with high quality and efficiency.Finally,in view of the fill point collaborative coverage algorithm is not applicable to high against the intensity of the scene of the large number of electronic warfare node and require the shortcomings of the paper put forward a cruise type field synergy covering method,through to the target area for double grid,and at every step in the optimization of objective function is introduced into comprehensive coverage gains weight and cost of turning,At the same time,the dead zone ring escape strategy is adopted to prevent the ew nodes from falling into the dead zone in flight,so as to realize the cooperative coverage of the open ground.Simulation results show that the algorithm has lower path repetition rate,less turning times and less energy consumption,and better practicability.
