Range-Doppler Measurements Based Target Locating for Active Radar Seekers

摘要：

This paper focuses on the estimation of the missiletarget relative position using range-Doppler measurements.Firstly,we analyze the observability of the relative position for different trajectories in depth,and arrive at a very interesting conclusion:the missile must have the acceleration component not aiming at target to obtain the 3-D relative position of the target.Secondly,the relative position estimation methods,using measurement series,is presented. Through the computation of Crammer-Rao Lower Bound,we can see the effects on the location errors of the observation series length,the initial missile-target range,the cross-range and radial velocity of the missile,and the cross-range acceleration of the missile,respectively.
