Abstract. It is shown that in the
conditions of small deletions of located objects from short-range radar characteristics
of the processed signal significantäí change when the object moves within the range of the meter. The
expressions for describing the shape of the radiation pattern of the radar
meter are presented and analyzed. Measurement errors of scalar information parameter
of useful signal is determined and the estimation of errors is given on the
background of non-Gaussian additive noise in condition of the changing range, taking
into account the radiation pattern shape meter, and depending on the nature of
the movement of located object. The scalar information parameter is the
frequency change of the useful signal, which carries information about the
speed of movement of located object. It is shown that the inclusion of
non-Gaussian nature of the additive noise which affects the measured
information parameters of the processed signal, can significantly increase the
potential accuracy of the meter.
Key words: radar meter, extended object, scalar information parameter, the radiation pattern, the additive Gaussian-noise ratio, signal to noise ratio, error of measurement
of speed.
