Abstract
A cost-effective FMCW radar equipment has a digital signal processor which controls at least one antenna through an oscillator and produces a mixed signal from transmitted and received signals modulated with a triangular waveform. The mixed signal is subjected to Fast Fourier transformation for each modulation phase (up and down) of each measurement cycle in order to obtain object frequencies, which are assigned to each target object, from the determined maxima. Object tracks which are formed from the object frequencies extend back over a plurality of measurement cycles and are used to form estimated values for those measured values of the object frequencies which are to be expected in the next measurement cycle. The mutually associated object frequencies of both modulation phases of a measurement cycle are determined and the distance and relative speed of each target object are determined from them.
