摘要: The invention discloses a sparse reconstruction-based broadband radar high-speed group-target resolving method, which comprises the following steps: 1, keystone transformation is carried out on echo signals of space group-target, realized through chirp-z transformation, and discrete spectrum SCZT (m, n) mth signal in Doppler ambiguity-existing range frequency domain obtained; 2, relationship between an observation data matrix XCZT two-dimensional complex amplitude GMN deduced; 3, G'(M*L)N time with different ambiguity times 4, problem detecting converted into optimization problem, plane drawn, coherent accumulation resolution group target can be realized.
