Abstract

A wideband PAR (phased array radar) implementation framework was proposed based on wide band digital intermediate frequency to solve aperture full time problem. A method was presented to compensate the aperture full time by digital stretch processing of chirp signal. A compensation approach was also put forward for RF (radio frequency) channels phase consistency with phase adjustment of digital oscillator. Experiment results based on hardware system indicate that the method is effective and engineering realizable, it can effectively compensate the inconsistency of aperture fulltime and RF channels.
