The invention refers to a method and device for wideband radar, the method comprising: -generating a wideband signal ( 1, 6 ) with a bandwidth B; -copying the wideband signal ( 1, 6 ); -transmitting the wideband signal ( 6' ); -receiving a returned echo signal ( 11 ) from the transmitted signal ( 6' ); -dividing the copied signal into a number, Nf, of subsequent frequency bands b; -manipulating the copied and divided signal into an anticipated signal ( 10 ) by adding a number Nd of anticipated delays and a number of ND Doppler stretches to the copied and divided signal for each Nf subsequent frequency band b; -dividing the received signal ( 17 ) into a number, Nf, of subsequent frequency bands b; -correlating corresponding frequency bands in the divided received signal ( 17 ) and the anticipated signal ( 10 ) giving NdND correlated signals ( 19 ) for determining range (R) to a target and velocity (v) of the target.
