Study on ionosphere environment online sensing for cognitive over-the-horizon radar

In the Over-The-Horizon Radar (OTHR), the sensing of the ionosphere environment is performed in additional process through a set of separate equipment, resulting low efficiency. On the idea of the cognitive OTHR, an approach to get the information of the ionosphere in the detection cycle is proposed in this paper, enabling the feedback from the receiver to the transmitter. Simulation results testify the validity of the method.
