The measurement performance of the dual-frequency correlation radar altimetry for the estimation of the sea wave heights is not as accurate in satellite as in airborne platform. Multi-frequency sensing signals can be applied to obtain sea surface state information while maintaining sensitivity over wide range of sea wave turbulences from space. The proposed method uses a sensing signal with angle modulation with optimum modulation index of m = 4.5, which enables to obtain a spectrum from 11 harmonics, instead of generating 11 frequency transmit signals for spaceborne multi-frequency radar altimetry. Maximum sensitivity of the measurement to the root-mean-square of the sea wave heights was obtained for the optimal frequency gaps between transmit signals.
