Abstract. Results of processing of signals of quasicontinuous
radiation and with linear frequency modulation by the radar station
accompanying group air object are presented. Possibility of superresolution of group objects on range and speed in pulse
volume is experimentally confirmed with classical and coherent methods of the
autoregression digital spectral analysis, and also the methods based on the
theory of statistical decisions. Features of superresolution of signals after preliminary digital processing
of signals in the conditions of their distortions are given in a send-receive
path of RLS, weighing of a bending-around pack of impulses in time, reflections
from a spreading surface, local subjects and screw components.
Keywords: superresolution, group air object, linear
prediction, theory of statistical decisions, linear frequency modulation,
vector of weight factors, time
function, spectral function, range strobe, frequency filter.
