Abstract: A method of reusing a frequency by allocating two orthogonal signal waveforms to the same frequency band is as follows. Two high-frequency ocean surface radars can be operated in the same frequency band without mutual interference by allocating a signal having an up-chirped LFM waveform and a signal having a down-chirped LFM waveform, having the same frequency band, to the two radars by employing an orthogonal characteristic between the two signals. Furthermore, a plurality of radars located within a distance within which interference is possible can be operated without mutual interference by combining and allocating two orthogonal signals and a plurality of frequency bands.
