Hypersonic speed target speed measuring method

摘要: The invention discloses a hypersonic speed target measuring method. method mainly solves the problems of complex emission frequency modulation signals, cross-distance unit correction echoes and unable ambiguity resolution in prior art. comprises steps emitting linear type continuous wave signals by radar array element; dechirping received echo data conducting fourier transform treatment on to obtain time-frequency matrix; constructing spectrum coordinate obtaining based spectral line searching method; finally figuring out to-be-measured outputting system. According technical scheme invention, measurement is achieved. simple signal emission, free correction, not fuzzy measurement.
