Abstract:
The whole airspace phased array telemetry, track and command (TT&C) system is regarded as the development tendency of next generation TT&C system, and the distribution of the antenna units and the beamforming technology have sparked wide interest in this field. A method for antenna distribution is proposed based on the linear subarrays technology. A symmetrical truncated cone conformal array is composed of the linear subarrays placed on the generatrix. The impact of truncated cone bottom radius and elevation angle on beamforming are studied and simulated. Simulation results verify the system design.
