摘要： The invention relates to a method for evaluating the direction of partial waves of at least one subscriber signal, wherein a plurality Ka receiver sensors are allocated to a receiver. Ka receive signals are picked up by the receiver sensors. Said signals are made up by at least a subscriber signal characterized by fine structure for each individual transmitter, wherein a k subscriber signal (k=1..K) is transmitted by partial waves with differing directions at the receiving point. Channel pulse responses allocated to the Ka receiver sensors are determined from the receive signals, and the direction of incidence of at least one partial wave is determined from the channel pulse responses. The inventive method can be used to advantageous effect in mobile telephone, radar, sonar or sismic measuring systems.
