Embodiment Construction

[0012] The main important contents of the present invention include establishing the target displacement calculation formula, constructing a quasi-Newton iterative calculation model, and assigning points and traces based on acceleration.

[0013] (1) Target displacement calculation formula

[0014] Since the time difference between the unassigned point track and the track is usually short, the update rate of typical navigation radar target data is usually about 3s, while the data update rate of early warning radar is higher and the finer cycle is shorter, so it can be assumed that the target is in a relatively short time. In a short period of time, the normal and tangential forces are uniform, that is, the target's normal and tangential acceleration values ​​are constant, and the present invention calculates the target's tangential acceleration a based on the following formula t and normal acceleration a n :

Abstract

The invention provides a plot correlation distribution method based on a quasi-Newton method. The plot correlation distribution method comprises the following steps: firstly, giving a displacement calculation formula of a flight path under the influence of tangential and normal accelerations on the basis of a uniform acceleration model; secondly, decomposing a displacement change formula to reducecalculation complexity, and establishing an iterative model for solving tangential acceleration and normal acceleration based on a quasi-Newton method; constructing an energy formula again to evaluate the influence degrees determined by different trace point distribution schemes; and finally, giving out a route cross avoidance rule and a minimum energy rule, optimizing a plot allocation scheme, and preventing a plot allocation error.
