✦ Synopsis

A pulse Doppler radar with one-dimensional direction sensiti¨ity is described. The system uses quadrature mixing to retain the direction information in an echo signal, and performs signal sampling o¨er a predetermined time slot to ignore reflected signals from objects outside the range of interest.

The output of a motion detector depends on the direction of pattern motion, relative to the axis defined by its two input elements. Usually a cosine shaped directional sensitivity characteristics is assumed: The response is strongest for pattern motion along the detector axis, reversing its sign for
