Latest Patents

Jianjun Ni holds a patent for an "Ultrawideband asynchronous tracking system and method." This passive tracking system incorporates multiple ultrawideband (UWB) receivers that operate asynchronously with respect to a UWB transmitter. The system's geometry utilizes several clusters, each containing multiple antennas. By determining the Time Difference of Arrival (TDOA) for the antennas in each cluster, the system can estimate the Angle of Arrival (AOA) based on a far-field assumption regarding the geometry. The design also includes parallel software communication sockets established with each UWB receiver, allowing for the processing of waveform data through the alternate reception of packets from each receiver. To enhance accuracy in noisy, multipath environments, Cross Correlation Peak Detection (CCPD) is employed to estimate TDOA information.
