The detection of slowly moving target in a strong backscattering background (clutter for radar, reverberation fo sonar) is a challenge to both Airborne Radars and Surface Ship or Submarine Sonars communities. In this paper, recent advances in the areas of waveforms design and beam-forming in those two domains will be described. In a first part, more efficient wide-band Doppler waveforms for sonar and radar moving targets detection will be presented. The second part will focus on the implementation of adaptive beam-forming for sonar and coloured transmission space time beam-forming for radar. Results on reverberation reduction obtained on a towed array sonar in CW mode will be discussed, and perspectives for coloured transmission radar systems will be outlined.
