METHOD FOR PROCESSING A FREQUENCY MODULATED INTERRUPTED CONTINUOUS WAVE (FMICW) RADAR SIGNAL

摘要

The present invention relates to a method for processing a Frequency Modulated Interrupted Continuous Wave (FMICW) radar signal: The method comprises following steps: generating a signal with a frequency changing over a set bandwidth, gating the signal on and off with a predetermined frequency (fg) thereby forming on-timeslots and off-timeslots, sending the gated signal to a desired target with help of a transmitter and an antenna, receiving a reflected signal during the off-timeslots of the gated signal, and detecting and gathering desired properties from the received signal during the off-timeslots of the gated signal. In accordance with the invention a desired portion of the off-timeslot is detected and/or processed during each off-timeslot of the gated signal in order to obtain information from a desired distance and in order to minimize the noise of the signal related to desired distance.
