    Abstract
  • The principle of full dimension and reduced dimension space time adaptive processing (STAP) was introduced. By analyzing torpedo′s working environment and mode, and its data structure, the possibility to improve target detection performance of acoustic homing torpedo under reverberation background with STAP method was discussed, and the solutions to the key steps and the basic flow of reverberation suppression using STAP were given. The analysis shows that reverberation suppression using STAP is more difficult than clutter suppression of airborne early warning(AEW) radar, but its implementation is possible. Simulation results show that better target detection performance can be achieved by using STAP method than by conventional method. STAP method can sufficiently utilize the reverberation space time distribution characteristics of acoustic homing torpedo, so it will be a prospective method for reverberation suppression.
