History
Then AN/SPG-55B adds a new high-power (1 megawatt), FM-swept, wide-pulse (26 microsecond) track transmitter, pulse compression techniques in the track receiver, and the use of pulse-to-pulse frequency diversity transmission. This combination of a high-power, FM-swept track transmitter and pulse compression techniques in the track receiver gives the radar the increased detection capability of the long pulse while still retaining the range resolution and accuracy of a short pulse. Frequency diversity transmission increases jamming resistance by forcing the jammer to spread its power over a wider band of frequencies.
