Abstract
The invention relates to an FM-CW radar apparatus where the frequency sweep duration (R) corresponding with the transmitted signal is increased to obtain a mixing signal which is operational in a wider frequency range than the frequency sweep of the transmitted signal. This has the effect that processing of echo signals of sufficient length can be realized, also from objects which are located near the limits of the radar range.
