The present invention relates to a method for focusing signals measured by a scanning radar system (6; 17) comprising at least one antenna (7; 19). The radar system is adapted to transmit radar signals forming at least one antenna beam (9, 1 1; 20) and to detect reflections of said at least one antenna beam caused by an object (15; 22) at a point of reflection. The method comprises the step of calculating an updated radar signal (S U 1 ; S U 2 ; S U 3 ) based on at least one measured radar signal (S P 1 , S P 2 ; S P ) and an antenna pointing error signal (e 1 ; e 2) which is also calculated based on the at least one measured radar signal. Then a signal adapted filter (h 1; h 2; h 3) is calculated based on any or both of the characteristics of the at least one antenna and at least one measured reference radar signal, and, finally, a focused radar signal (S F 1 , S F 2 ; S F 3) is calculated by filtering the updated radar signal using the signal adapted filter. |
