Abstract
The invention refers to a method and device for wideband radar, the method comprising: —generating a wideband signal () with a bandwidth B; —copying the wideband signal (); —transmitting the wideband signal (); —receiving a returned echo signal () from the transmitted signal (); —dividing the copied signal into a number, N, of subsequent frequency bands b; —manipulating the copied and divided signal into an anticipated signal () by adding a number Nof anticipated delays and a number of NDoppler stretches to the copied and divided signal for each Nsubsequent frequency band b; —dividing the received signal () into a number, N, of subsequent frequency bands b; —correlating corresponding frequency bands in the divided received signal () and the anticipated signal () giving NNcorrelated signals () for determining range (R) to a target and velocity (v) of the target.
