Optimization of target designation for air-ship missile under condition of bearing-only attack

Bearing-only attack is one of the most effective approach for air-ship missiles to adapt complex electromagnetic combat environment. Because of the absence of target distance information, the target designation and the fire control parameters are hard to be solved. Based on the analysis of quantization error of airborne sensors, the optimized estimation method of target parameters based on the measurement of target rotation speed by the airborne sensors was proposed. The error of the original and optimized estimation method was analyzed and compared. The distribution of locating precision in polar coordinates of the proposed method was simulated by the approaches of airborne passive radar and omnibearing warning system. The simulation shows that there are error divergence domains determined by the orientation of target and the quantization error of airborne sensors. Further more, the optimized maneuver strategy of battleplanes under the condition of bearing-only attack was proposed, which suggests that battleplanes be out of the divergence domains, and be away from these domains as far as possible.
