An approach of track managements system in software defined radar

Abstract

Each multi target tracking system must have a track management procedure. It is an integral part of tracking systems and often used together with data association, state estimation and other parts of systems. On the other hand, the family of C-band frequency agile, low to medium altitude pulse Doppler air search radars, are designed to detect low-altitude, low cross-section aircraft targets in conditions of clutter and electronic countermeasures. Within the framework of its modernization, the receiver is conceived on the basis of software defined radar. The implementation of target tracking system within software defined radar, is also suggested. The paper describes the procedure of track management system procedure in the framework of multi target tracking system. It includes complete procedure of initialization, maintenance and deletion of tracks. Part of the numerical experiments is given at the end of the paper, in order to describe a good property functional of the TMS system

An approach of constant false alarm ratio for improved target tracking

“…In each scan, a number of false tracks are initialized. In that situation, the first thing the tracking algorithm should do is discriminate or separate between the real and false tracks [18,19].…”

Contribution to determining the limits of the efficiency of target tracking

“…The single target Integrated Track Splitting (ITS) [10] and multitarget Joint ITS (JITS) and Linear Multitarget ITS (LMITS) [11] are generalizations of IPDA [11], JIPDA and LMIPDA respectively [12,13]. They more precisely approximate the trajectory state by the Gaussian Mixture.…”
