Latest Patents

Lei Lei's latest patents include a method for designing a sparse array for automotive radar using particle swarm optimization. This innovative method involves moving antenna elements to candidate neighboring grid positions, starting from an initial random seed placement. The goal is to iteratively search for an optimal placement that improves upon a cost function derived from the FFT response characteristics. The process is repeated for numerous random seed placements to identify the candidate placement with the lowest cost function.

Another notable patent is the sidelobe subtraction method in automotive radar signal processing. This method addresses the issue of sidelobes that can obscure weaker targets in the presence of stronger ones. By estimating and subtracting the sidelobes from the measured FFT response, Lei's method enhances the visibility of additional targets that may have been previously buried. This iterative approach ensures that the desired sidelobe residual level is achieved, improving the overall effectiveness of radar systems.
