Estimation of the Range and Its Derivatives in an Active Two-Position Radar System

Multipurpose Tracking in Multiposition Radar Systems

“…(4) All basic decision-making rules can be obtained using the example of a two-position radar (TPR) with exchange of measurements [6] in the tracking of two AOs. The geometry of the relative position of radar 1, radar 2, and the AO and is shown on Fig.…”

“…(6) For current estimation of the coordinates, a second-order analog-discrete filter is used [6], making it possible for a linear process of the form in the presence of measurements…”

“…Similar coordinates formed from measurements of the second position of radar 2, converted to the first position of radar 1, are determined by the relations (5) for the first AO and (6) for the second AO, where , are, respectively, the courses of radar 1, radar 2 and relative bearings of the AOs.…”

“…(5) the spatial and relative positioning of positions vary in time; (6) in order to control the attitude of the positions, information on the AO's location must be formed continuously.…”

“…The first feature determines the need to bring all measurements formed at each position to a single coordinate system with a common origin. The remaining features predetermine the necessity of using analog-discrete filtering algorithms [6,7].…”
