  • Processing of concatenated radar measurements to re-establish signal phase coherence
    Patent number: 4996534
    Abstract: A method and apparatus for re-establising frequency, phase and amplitude coherence for radar samples generated by mutiple frequency transmitter pulse trains. A plurality of transmitter means 10-12 produce pulses of different frequencies and an antenna 22 and waveguide 24 direct the pulses 26 towards the aircraft 30. The reflected radar signal 32 returns to the antenna 22 l and waveguide 24 and is measured by the receiver 14. The reflected radar signal is then frequency rescaled, phase realigned, and amplitude normalized by the computer processor 18 and output to a processor/display unit 20.
