Abstract
An array of transducer elements receives energy from a target or targets in a field of view and operates on the transducer outputs to provide a plurality of different levels of shading. The most useful portion of the field pattern is selected and combined with other most useful portions of other field patterns into a single composite display which results in one or more relatively narrow lobes, indicating targets, and without the presentation of side lobes which may be masking targets.
Claims12
A detection system, comprising:
- A) an array of transducer elements, each operable to provide an output signal in response to energy received from a target area under observation;
- B) means including beamformer means operable in response to all of said output signals of said transducer elements to apply different levels of shading function thereto to derive a plurality of different field pattern signals;
- and
- C) means for selecting different predetermined portions from said plurality of field pattern signals and combining said predetermined portions into a single unitary composite field pattern signal.
