Claim 6:
7. A method of generating an orthogonal radar signal based on frequency modulation, the method comprising:
generating a set of coded frequency-modulation waveforms through element operation between a set of frequency-modulation waveforms and a polyphase code set; and
calculating an objective polyphase code set or an optimized polyphase code set based on a domain parameter that minimizes an objective function for the set of coded frequency-modulation waveforms,
wherein the objective function is calculated by a sum of a value, which is obtained by multiplying an autocorrelation sidelobe peak for the set of coded frequency-modulation waveforms by a first weighting factor value, and a value, which is obtained by multiplying a cross-correlation peak for the set of coded frequency-modulation waveforms by a second weighting factor.
