Circuit arrangement for improving accuracy of angular measurements in radar systems

摘要

To improve the accuracy of angular measurements in a radar system by suppressing noise due to target glint, an angular-deviation signal . epsilon. derived from the output signals &Sgr; and &Dgr; of a sum channel and a difference channel is gated so as to be read only when the sum signal &Sgr; is at or near a maximum. In a more elaborate embodiment, passage of the deviation signal &egr; is also blocked when a quadrature-deviation signal &egr;q, likewise derived from the sum and difference signals &Sgr; and &Dgr;, has an absolute magnitude above a preferably adjustable threshold.
