  • US Patent:
    51247089, Jun 23, 1992
  • Filed:
    Feb 25, 1991
  • Appl. No.:
  • Inventors:
    David C. Mackes - Catonsville MD
    Franklin B. Jones - Catonsville MD
  • Assignee:
    The United States of America as represented by the Secretary of the Air
    Force - Washington DC
  • International Classification:
    G01S 740
  • US Classification:
  • Abstract:
    The disclosed system comprises a testing system which measures the stability of a moving target indicator radar transmitter. It automatically measures the imperfections of its internal in-phase (I)/quadrature (Q) demodulator, and it consists of a control computer, a synchronizer, a frequency synthesizer, an IQ demodulator, a low noise amplifier and a waveform recorder. A unit under test is inserted across the test set for measurement and calibration. The system set has the following features: (a) An automatic calibration routine that requires a tunable RF source. This source provides the RF drive to the UUT. (b) A discontinuous analog to digital (A/D) sample clock that has a precise controllable relationship with the RF pulse. The A/D sample clock samples only during the presence of the RF. (c) A method for computing stability using a table of amplitude and phase weighting coefficients and pulse positions.
