Detection algorithm for radar high speed weak targets
Jun Wang · Systems engineering and electronics · 2008
A short time slip window coherent integration and track-before-detect(TBD) based algorithm is proposed for the detection of radar high speed weak targets,the presented algorithm is based on short time slip window coherent integration and dynamic programming.Firstly,radar echoes are formed into a first in first out queue,and short time slip window coherent integration is implemented.Secondly,an improved track-before-detect(TBD) algorithm based on dynamic programming is performed to detect the target trace.Meanwhile the cascade transform states are estimated to reduce the influence of fluctuating target amplitude on detection performance.The simulation of real data shows the feasibility and efficiency of this algorithm in reducing computation as well as improving the detection performance of weak radar targets.
