Abstract:Regarding the issue of large frequency offset estimation and compensation in bidirectional stable communication between radar and ultra-high speed projectile command guidance in information weapons, a command waveform design was proposed. Frequency offset estimation and compensation in the range of -468.75 kHz to 468.75 kHz can be achieved by utilizing the frequency offset sensitivity of M sequences and long/short interval Zadoff-Chu sequences. The stable up-channel and down-channel communication between radar and ultra-high speed projectile is ensured. Finally, the effectiveness of the proposed method is verified through matlab simulation.
