Title: HYBRID RADAR INTEGRATED INTO SINGLE PACKAGE
Abstract:
A radar apparatus includes a phased array receiver, with a steerable receive beam. The receiver elements are grouped into subarrays, which each provide a subarray signal to a mixer. The mixer signals are then used by a DBF algorithm to determine narrow virtual beams within the receive beam. The receive beam is used to obtain radar data from sectors of the field of view, and the sectors may be approximately as wide as the receive beam. The order in which sectors are examined may be determined by the sector importance, related to the presence, nature, and/or behavior of previously tracked targets within each sector.
