ABSTRACT:
A radar system includes signal processing means (SP) operable to determine the velocity relative to a receiving antenna (AR) of each object from which transmitted radiation is reflected. The signal processing means delivers signals representing the relative velocities of objects in each of a number of predetermined ranges of velocity values. Storage means (SM) are provided which comprise, for each increment of antenna bearing, a separate storage location for each of the ranges of velocity values. Circuit means (CM) are operable to read out the contents of the storage means and to modify signals delivered by the signal processing means (SP) in accordance with the contents of the storage means (SM) to provide output signals. In addition the circuit means (CM) is also arranged to further modify the output signals to provide new contents for the storage means.
