Method and system for radar measurement of object speeds and coordinates (modifications) Method and system for radar measurement of object speeds and coordinates (modifications) / 2255352
The method is accomplished by radiation of a continuous frequency-modulated sounding signal, reception of the reflected signal in one or several spatial positions, multiplication of it with the radiated signal and subtraction of the matrix of the values of the correlation functions of the obtained homodyne signal and the two-dimensional (range, speed) matrix of the base signals formed of the modulating signal. The ranges and speeds of the detected objects are computed according to the number of the elements of the matrix of the correlation functions, in which the values of the correlation functions exceed the threshold level. The value of speed is specified by subtraction of the frequencies of the spectrum components of the correlation signals obtained as a sequence of values of the correlation function values during the time of signal accumulation. At reception of the reflected signal in several spatially spaced positions a three-dimensional (range, speed, angular coordinate) or four-dimensional matrix of base signals is formed for each position, and, according to the numbers of the respective matrix summary to the positions of the correlation functions, the range, angular co-correlation functions, the range, angular co-ordinates and speeds of the detected objects are determined. The system for measurement of speeds and co-ordinates of the objects has an antenna-feeder device, homodyne transceiver correlometer forming the matrices of the base signals and computing the functions of correlation and correlation signals, and a processor forming the modulating signal and computing the object speeds and coordinates.
