Latest Patents

Jianfeng Li holds a patent titled "Method for jointly estimating gain-phase error and direction of arrival (DOA) based on unmanned aerial vehicle (UAV) array." This method involves equipping each UAV with an antenna to form a receive array through a swarm of multiple UAVs. The process includes changing the array manifold through the movement of UAVs while maintaining a constant observation baseline. By calculating a covariance matrix for each sensed source signal and obtaining a corresponding noise subspace through eigenvalue decomposition, the method constructs a quadratic optimization problem. This leads to the joint estimation of gain-phase error and DOA through spectrum peak search, ultimately improving the accuracy of passive positioning.
