摘要: A method and system for mapping ocean currents with a single radar. The radar is a pulsed monostatic radar operating in the HF/VHF range using a single transmitting antenna with a wide beam width. There is a linear array of antennas, each with its own receiver/digitizer system to sample the complex signal. The summing and phasing of the signals is done in software. The correlation functions are calculated using two successive complex Fourier transforms. The current vectors are measured as a function of range and angle from the radar site, thereby generating the current map.
