Abstract
This paper addresses cascading an adaptive spatial preprocessor for wideband noise jammer suppression with a space-time adaptive processor in airborne radar systems. A new approach, utilizing a frequency sideband, next to but distinct from the radar's signal bandwidth (i.e. mainband), to obtain jammer-only training data for pre-suppression of jammers in the main-band is demonstrated. This approach offers greater flexibility and performance potential to radar design, because the collection of training data is not restricted to specific range gates or Doppler regions as in the case of low and high PRF systems. However, since the weights for jammer suppression are derived from data with a carrier frequency different from the radar signal, compensation techniques are developed which can provide ample jammer suppression in the radar's mainband.
