  • Digital compensation for amplifier-induced instability
    Patent number: 10324169
    Abstract: A method is provided for correcting radar signal transient variation induced by power amplification in a pulse radar transmitter. The method includes establishing a first plurality of characteristics of a first pulse sequence having a digital pulse; establishing a second plurality of characteristics of a second pulse sequence having a plurality of digital pulses; comparing the first and second pluralities of characteristics to determine a sequence difference; providing pre-distortion coefficients for the plurality of digital pulses corresponding to the signal transient variation in response to the sequence difference; and applying the coefficients to the plurality of digital pulses prior to the power amplification.
    Type: Grant
