摘要： 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.

摘要： A microwave lens having an array of electronic inductive capacitive cells wherein each cell includes an electrically conductive pattern which responds to incident microwave electromagnetic energy as an LC resonator. At least one of the cells includes at least one MEMS device which is movable in response to an electrical bias to thereby vary the resonant frequency of that cell. In order to bias the MEMS device, an electrical insulating layer extends along a portion of the pattern of the cell and to both sides of the MEMS device. An electrically conductive strip then extends over the insulating layer so that the conductive strip is electrically insulated from the pattern while electrically connected to the MEMS device.
