Embodiment Construction

[0128] Target exercise state setting:

[0129] In this implementation plan, the target performing a dive movement in a two-dimensional plane is considered. Its initial position is [60km 50km]; the initial velocity is set to [350m / s, 0m / s]. The motion model includes two: acceleration (CA) and constant speed (CV); uniform motion is performed between 1-60s, 75-125s and 140-200s respectively, uniform acceleration is performed at 60-75s and 125-140s, 60-75s , the accelerations in the two directions are: a x =-2.2m / s 2 , a y =-2.2m / s 2 ;The accelerations in the two directions at 100~115s are respectively: 2.2m / s 2 , a y =2.2m / s 2 . Total radar tracking time: 200s; minimum sampling period: 0.5s. An optional collection of adaptive parameters:

Abstract

The invention discloses a co-location MIMO radar object tracking method with combined space-time resource management, belongs to the object tracking field, and specifically relates to a multi-object tracking radar resource dividing method; the method considers the time domain and spatial domain system resource distribution problems in a process in which the MIMO radar tracks a maneuvering object;the method ensures the object tracking precision, adaptively adjusts a sampling period and subarray dividing number work parameters, thus saving system resources; the algorithm uses a nonlinear measurement transition maneuvering object tracking algorithm as the basis, and combines with a space-time resource management strategy, thus providing higher tracking precision and combat efficiency under aMIMO radar maneuvering object tracking scene.

Description

technical field [0001] The invention relates to the field of target tracking, and mainly aims at the problem of space-time resource management in the process of maneuvering target tracking of co-location MIMO (Multiple-Input Multiple-Output) radars. It is specifically applied in the process of maneuvering target tracking of nonlinear measurement, adaptively adjusts the sampling period and the number of sub-array divisions, and realizes the optimal allocation of space-time resources for co-located MIMO radars. Background technique [0002] In recent years, MIMO radar has attracted extensive attention due to its advantages in target detection parameter estimation, resolution capability, and interference suppression capability. (D.J.Rabideau and P.Parker, "Ubiquitous MIMOmultifunction digital array radar and the role of time-energy management inradar," MIT Lincoln Laboratory, Lexington, MA, USA, Project Report DAR-4, Dec.2003.) MIMO radar can be divided into There are two type...
