Method for measurement of range and Doppler frequency shift in radar station (RLS) with quasi-continuous radiation is in the fact that for measurement of coordinates of targets one performs sounding of space with several packs of simple radio-pulses with different periods of signal following, in the massif of voltages of received signals of the first period of sounding one carries out sequential search of local maximum of signal of the-th target, one performs sequential search forof composition of indicesof range for each on-off ratio and by the numbers of strobes obtained one determines unique range to the-th target. At that the massif of voltages of received signals of the first period of sounding is formed in four-dimensional form, with bringing into correspondence of combination of indicesby coordinates of range, azimuth, angle of elevation and Doppler frequency, with reveal of signal reflected from the-th target carried out according to logical rule:,With fixation of respective compositions of indicesof local maxima in massifs of voltages of probing signals with on-off ratio, and value of Doppler shift of frequency is calculated by formula:,where- width of frequency filter for package with-th period of sounding;- function of measurement of Doppler frequency shift by index of mainand additionalchannels and voltages of those. |
