Abstract
A dual scan rate radar system (DSR) including a phased array antenna, a tsmitter, 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..sub.S and the short-range pulse is transmitted into a fast beam at .theta..sub.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..sub.S and .theta..sub.F are varied so that the slow and fast beam are scanned at dual rates R.sub.S and R.sub.F, respectively, where R.sub.S <R.sub.F.
