A dual scan rate radar system DSR including a phased array antenna, a transmitter, a receiver and a control unit. Each rf pulse from the transmitter includes contiguous long-range and short-range pulses. The control unit adjusts the antenna so that the long-range pulse is transmitted into a slow beam at theta s and the short-range pulse is transmitted into a fast beam at theta F. The control unit also adjusts the antenna to receive the short-range pulse echos during a first part of the interpulse interval and the long-range pulse echos during a second part of the interpulse interval. The angles theta S and theta F are varied so that the slow and fast beam are scanned at dual rates RS and RF, respectively, where RS RF.
