Using the line of sight velocities measured by Arecibo dual-beam incoherent scatter radar (ISR), an analysis of tidal waves in the altitude range from 90 to 150 km for the January 14-23, 2010, period is presented. This is the first time that dual-beam ISR is used for E-region tides and planetary wave studies. Firstly, a linear regularization method is applied to the Arecibo line of sight velocities. This method relaxes old method’s restrictive assumption that a vector field remains constant while the antenna rotates in azimuth. Secondly, we use Lomb-Scargle spectral analysis to derive dominant oscillation modes in ISR measured neutral winds. The result shows that multiple oscillation modes happened on ISR running period. Thirdly, a new constrained harmonic fitting is used to study diurnal, semidiurnal, terdiurnal tides, and the quasi-two-day planetary wave. Those harmonic components are fitted with different combinations simultaneously. Finally, we contrast our results with previous Arecibo and model results. The combination of using dual beam configuration, applying linear regularization and constrained fitting should make the results obtained here more accurate than before.
