Abstract: The present invention relates to a method for frequency sharing of a high frequency ocean surface radar, which assigns two signal waveforms orthogonal to each other to the same frequency band so as to reuse the frequency, and an embodiment of the present invention is as follows. Two radars can be operated without interfering each other in the same frequency band by assigning an up-chirped linear frequency modulation (LFM) waveform signal and a down-chirped LFM waveform signal of the same frequency band to the two frequency ocean surface radar, respectively, using the characteristics of the two waveform signals orthogonal to each other. In addition, multiple radars located within the distance possible to be interrupted can be operated without interfering with each other by combining and assigning multiple frequency bands and the two orthogonal signals to the radars. Because the frequency reuse technique of the present invention continuously uses chirped LFM signals without time division, continuous real-time observation over a large region is possible and thereby the accuracy of obtained information on an ocean surface is raised. Efficient frequency reuse is achieved by combining two LFM signal waveforms, which have a characteristic of being orthogonal to each other, with multiple frequency bands.
