Abstract: We compare, both theoretically and practically, bi\|phase inter\|pulse coded pulse train radar waveforms containing different pulse shapes. These waveforms can be employed in the Wuhan ionosphere comprehensive sounding system (WICSS). Compared with bi\|phase inter\|pulse coded rectangular pulse train waveforms, bi\|phase inter\|pulse coded Gaussian pulse train waveforms can achieve higher spectral effciency and range accuracy, better range resolution, and the same Doppler resolution. It is specially suitable for ionosonde. The simulating and experimental methods used in this paper are also suitable for other radar waveform comparison.
