Abstract

The reflection signals of each transmitter (30) are able to be subsequently processed to create a virtual receiving array of receiver elements. The number of the virtual receiver elements in the virtual receiving array corresponds to the number of receiver elements (34) multiplied by the number of real transmitter elements (30). The virtual array of receiver elements is divided into identical sub-arrays. Following the formation of sub-arrays, covariance matrix data for each of the sub-arrays are generated based on the reflection signal. The covariance matrix data are spatially smoothed by means of averaging thereof to decorrelate the direct reflection signal from the object and multipath reflection signal among the reflection signal. As a result, the direct reflection signal from the object and multipath reflection signal are resolved.
