Abstract:
A process for evaluating the radar pattern of a phased array antenna assembly radar system, comprised of a radar source, wherein said process utilizes transmissions from a global positioning satellite, and wherein said process utilizes a delayed radar target on a moving platform, a remote differential global positioning receiver on said moving platform, a fixed global positioning receiver on said phased array antenna, and a data link between said remote differential global positioning receiver and said fixed global positioning receiver, comprising the steps of:(a) radiating a first signal from said radar source towards said delayed radar target, (b) receiving a first radar reply at said phased array antenna assembly from said delayed radar target, (c) receiving a second signal from said global positioning satellite at said remote global positioning receiver, (d) receiving a third signal at said fixed global positioning receiver from said remote global positioning receiver, (e) transmitting a fourth signal from said global positioning satellite to said fixed global positioning receiver, and (g) processing said first signal, said second signal, said third signal, and said fourth signal in a computer.
