Discusses the application of Minimum Variation Method (MVM) in extracting sea echo's space spectrum from HF Ground Wave Radar (GWR) 's detection. Numerical simulation with a broad beam model sea echo shows its validation. Experimental data had been processed and the extracted currents information was compared with what yielded from the U.S. Codar system and the in situ measurement with traditional means. The correspondence relationship between sea echo's SNR azimuthal distribution and the array's effective viewing angle is verified.
