Abstract
A vehicle-based method of determining the extent to which a target object is a single point scattering center is provided, wherein the vehicle comprises a radar system including at least one radar transmit element adapted to send a radar signal towards the target object, and a plurality of receiver channels (elements or antennas), each being adapted to receive radar signals reflected from the target object. According to the method, a radar signal is transmitted from the at least one radar transmit element to the target object, and signals being reflected by the target object are received at the receiver channels. A frequency transformation of the reflected signals is performed in order to create a range-Doppler map for each of the plurality of receiver channels. Furthermore, a beam vector is generated by selecting a respective value from each of the range-Doppler maps as an element of the beam vector corresponding to a respective receiver channel. The beam vector is processed by a Fourier transform and a peak amplitude from the Fourier transform is calculated. Finally, a reference value is calculated which depends on the elements of the beam vector, and the peak amplitude is compar…
