UWB RADAR MEASUREMENT EVALUATION METHOD AND ARRANGEMENT
Abstract:
It is described a method of evaluating radar measurement data, the method comprising: forming plural subsequent channel impulse response profiles (14) from radar signals (6) across subsets of plural subsequent sample time intervals (15), the radar signals (6) being received due to reflection and/or interaction of plural UWB radar radiation pulses (3) transmitted towards a target (4); identifying, in each of the plural channel impulse response profiles (14), one of the plural sample time intervals (15) as a target sample time interval (16) in which received radar signals (6) are comprised originating due to reflection from the target (4); evaluating plural total radar signals of interest (17), each defined as respective magnitude and phase of the plural channel impulse response profiles (14) at the target sample time interval (16), in order to determine for at least one total radar signal of interest a phase (Φ) of a target contribution (21) to the total radar signal of interest (17); determining location and/or movement information of the target (4) based at least on the at least one phase (Φ) of the target contribution (21).
