Modular Transmitter Design For The AN/FPS-85 Phased-array Radar
The AN/FPS-85 is a large fixed-position phased-array radar located east of Eglin AFB in Florida (see Figure 1). The radar consists of separate transmit and receive arrays located in adjoining wedge-shaped buildings facing south toward the Gulf of Mexico. A matrix of separate transmit modules arranged in a 72-row by 72column matrix make up the transmit array for a total of 5,184 transmit elements. The radar transmit beam is steered electronically by phase differentials between adjoining rows and column beam steering signals. Each transmit module is rated for a maximum RF output of 10 kW peak at a maximum duty cycle of 0.005. "Graceful degradation" of performance of the vacuum tubes over time reduces the transmitter output to a mean peak power of about 5-6 kW for a total radar output peak power of about 32 MW'.
