Abstract
A process for evaluating the radar pattern of a phased array antenna subsystem by utilizing transmissions from a global positioning satellite. This process utilizes a delayed radar target on a moving platform, a remote differential global positioning receiver on the moving platform, a fixed global positioning receiver on the phased array antenna, and a communication data link between the remote global positioning receiver and the fixed global positioning receiver. In the first step of the process a first signal is radiated from the radar source towards the delayed radar target, then a first radar reply is received from the delayed radar target, then a second signal is received from the global positioning satellite at the remote global positioning receiver from the global positioning satellite, and then a third signal is received at the fixed global positioning receiver from the remote global positioning receiver, via the GPS data link, and then a fourth signal is transmitted from the said global positioning satellite to the fixed global positioning receiver.
