Abstract:
In a search radar including means operative to transmit and receive radar signals for a plurality of predetermined scan angles within a search scan; means operative to generate a plurality of signals representative of said predetermined scan angles; and means operative to generate a plurality of target amplitude measurement signals derived from said received radar signals respectively corresponding to said plurality of predetermined scan angles, the improvement of apparatus for estimating the target angle within a search scan comprising:first means operative to compute an intermediate signal for each prespecified angle of said plurality in accordance with a first function based on said generated angle signal and said generated target amplitude measurement signal correspondingly associated therewith;second means operative to compute signals representative of moment relationships of said corresponding plurality of prespecified scan angle signals and intermediate signals for a search scan of said radar; andthird means operative to compute a signal representative of said estimated target angle for a search scan in accordance with a second function based on the correspondingly associated moment related signals of said search scan computed by said second means.
