Patent

CA 2430695

An adaptive broadcast radar system for tracking targets is disclosed. The radar system includes a transmitter having sub-apertures and a receiver having sub-apertures. The transmitter sub-apertures generate and code a signal waveform. The signal waveform is coded with data about the transmitter, including the dregrees of freedom. The receiver signals that may include direct path signals and scattered signals correlating to the signal waveforms from the transmitter. The receiver includes a signal processor that regenerates a transmit beam for the coded data, delay, and doppler information from the received signals. The signal processor data quads encapsulates the information.

L'invention concerne un système de radar de diffusion adaptatif permettant de suivre des cibles. Ce système de radar comprend un émetteur-récepteur doté de sous-ouvertures et un récepteur possédant également des sous-ouvertures. Les sous-ouvertures de cet émetteur-récepteur génèrent et codent un oscillogramme de signal. Cet oscillogramme de signal est ensuite codé au moyen de données concernant l'émetteur-récepteur, comportant différents degrés de liberté. Les signaux de récepteur peuvent comprendre des signaux de chemin direct et des signaux éparpillés en corrélation avec les oscillogrammes de signal provenant de l'émetteur-récepteur. Le récepteur présente un processeur de signal qui régénère un faisceau d'émission pour les données codées, le délai et les informations de Doppler provenant des signaux reçus. Les quadruplers de données de processeur de signal renferment les informations.
