Alternative modes to modulate the signal of the space-based radar altimeter are compared. Expressions are obtained for the potentially achievable error variances of estimates of the delay of the reflected signal. The superiority of the MSK-mode over a traditional LFM in the height measuring accuracy, both conditioned by equal spectral efficiency, is corroborated. It is demonstrated that the equivalent energy gain of MSK against LFM may be up to 3 dB and more.
