Narrow band automatic phase control tracking circuitry |
摘要 |
The invention disclosed herein relates in general to an improved circuitry for narrow band frequency tracking system for doppler radar and includes third order phase lock loop circuitry to improve tracking techniques. This enables tracking input frequency variations caused by target maneuvers with substantially smaller tracking bandwidths than is currently possible.
