Title:
RADAR SYSTEM
Document Type and Number:
WIPO Patent Application WO2003048802
Kind Code:
A3
Abstract:
The invention relates to a radar system which emits a frequency-modulated emission signal (T(t)) and receives a reception signal (R(t)) reflected by at least one object, in order to determine the speed and/or the distance of at least one object to be located. In order to reduce or eliminate fading effects, the inventive radar system carries out at least one frequency shift (DELTAfswap1, DELTAfswap2 and DELTAfswap3) of the frequency-modulated emission signal (T(t)).
