  • Multiple channel electronic countermeasures radar receiver
    Patent number: 4215344
    Abstract: 1.
    Type: Grant
    Filed: November 15, 1963
    Date of Patent: July 29, 1980
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventor: Calvert F. Phillips, Jr.
  • Radar pulse phase code system
    Patent number: 4196435
    Abstract: A radar system for reducing the effective width of a transmitted pulse without increasing power utilizing coded phase shifting. Discrete parts of the transmitted pulse are phase shifted 180.degree. and upon return to the receiver the pulse is decoded by a sequence of delay lines and phase shifters positioned in accordance with a predetermined code rendering all the discrete parts in phase which are then summed.
    Type: Grant
    Filed: August 21, 1967
    Date of Patent: April 1, 1980
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventor: Calvert F. Phillips, Jr.
  • Frequency agility radar
    Patent number: 4038659
    Abstract: A frequency agility radar having automatic electronic front end tuning in synchronism with the transmitter on a pulse to pulse basis is provided. The automatic electronic front end tuning is achieved by the use of a backward wave parametric amplifier. The frequency generated by the radar transmitter is employed to control the center frequency of backward wave amplifier. The backward wave amplifier operates as an electronically tuned filter with the center frequency of the tuner following the radar frequency accurately.
