用于多源信息中制导的MM-LS时间配准算法

doi:10.3969/j.issn.1001-2400.2014.04.028

Abstract

Abstract:

The application of LS time registration has been restricted by both the assumption of the uniform motion of the target and the assumption that the ratio of the registration period to the sensor sampling period is an integer. The MM-LS time registration algorithm under no restriction has been studied in this paper. Based on the model of the uniform accelerated motion and accelerated linear motion, the MM-LS time registration algorithm has been obtained with the rule of MMSE. With the first order, second order, and third order derivative achieved through each model, the problem of non-integer ratio is solved by the extrapolating algorithm. Simulations indicate that the performance of MM-LS is always reliable when the maneuver overload of the target changes from 1g to 9g, and that the precision of radar changes from 10m to 100m.
