Abstract


This dissertation develops research work for some fields in which ground clutter suppression algorithm may be used for airborne phased-array radar, software design of 3DT-∑△- STAP algorithm with adaptive space-frequence steer vector algorithm is completed for clutter suppression realtime processing system based on TigerSHARC TS101 chip. The main work in this dissertation can be summarized as follows:1. We Analyzed the the distribution characteristics of ground clutter returns in airborne phased-array radar, and constructed the airborne phased-array radar main-lobe returns model .2. We Summarized the main methods of airborne radar clutter suppression and analyzed their performance and characteristics by much simulating.3. we Summarized two∑△- STAP methods of airborne radar clutter suppression , analyzes their performance and characteristics by much simulating.4. A new technique of clutter suppression be developed which is base on 3DT ?∑? ? STAP method with adaptive space-frequence steer vector. By simulating the new technique and 3DT -∑△- STAP for low-speed target detecting performance show that the performance of new technique is higher than 3DT-∑△- STAP.5. We Researched the feasibility of the technique.Realized the technique on TigerSHARC TS101 EZ-KIT system and got a preferable effect.Resovled a problem of matrix inverse by selecting a inverse algorithm applied on low order and high density martrix.
