  • A novel algorithm using multilayer reconstructed-autocorrelation is proposed for range tracking with short time signal in powerful noise on a short-range millimeter wave radar. This algorithm can solve the problem of weak anti-jamming ability and low accuracy in range tracking brought by above conditions, which reconstructs a data sequence by rearrangement autocorrelation of the observed data vector and then range information can be got by doing spectrum analysis. By using of this algorithm, straining noise and analyzing the spectrum are organically combined. Not only are the estimate precision is increased by exponential but also the frequency stability is greatly improved. The simulation results test and verify the theoretical analysis result and the algorithm effectiveness.
