PHASED ARRAY RADAR SYSTEM FOR TRACKING

The present innovation relates to a phased array radar system for tracking. The system comprises the following units: a track initiation unit (6) which initiates new tracks. A to the track initiation unit connected track prediction unit (1) which predicts the expected position and the calculated positional uncertainty of the target at the next measurement as a function of the time and the minimal, maximal and optimal measurement time difference to the next measurement. A to the track prediction unit (1) connected scheduling unit (2) which performs an independent calculation of a sequence of possible time intervals to the next measurement for each one of two conditions, namely that the measurement time difference will be placed between the calculated minimal and maximal time differences and that range-unambiguity will prevail, and then performs an intersection operation on the so-calculated sequences of time intervals with the purpose of calculating the optimal time intervals to the next measurement. A to the scheduling unit (2) connected track selection unit (3), which selects that track which has shortest time interval, Ki, to the next measurement and decreases the time interval to the next measurement for all other tracks with Ki. A to the track selection unit (3) connected transmitter/receiver unit (4) which forms the waveform, directs the beam, is designed to register the echo from the target and calculate, in a known manner, distance, speed, bearing and uncertainty in the distance and speed calculation, which values are transferred to the track prediction unit (1) for the further calculations in this unit. La présente invention se rapporte à un système radar de poursuite à antenne réseau à commande de phase. Ce système comprend les unités suivantes: une unité de déclenchement de poursuite (6), qui déclenche de nouvelles poursuites. Une unité de prédiction de poursuite (1), qui prévoit la position vraisemblable et l'incertitude de position calculée de la cible lors de la mesure suivante en fonction du temps et de la différence temporelle de mesure minimale, maximale et optimale. Une unité de calcul (2) raccordée à l'unité de prédiction de poursuite, qui effectue un calcul individuel d'une séquence d'intervalles de temps possibles en fonction de la mesure suivante pour chacune des deux conditions, à savoir que la différence temporelle de mesure se situera entre les différences temporelles calculées, minimales et maximales et que la non ambiguïté de port
