An ISAC-ISAR Imaging and Tracking Method for Moving Target Sensing

The integrated sensing and communication (ISAC) is a significant feature in the 6G communication network owing to its monitoring capability around the base station. Meanwhile, inverse synthetic aperture radar (ISAR) imaging technology can obtain two-dimensional image of moving targets with fixed antenna. Inspired by this, an ISAC-ISAR imaging and tracking method is proposed for blind moving target sensing in this paper. First, the ISAC-ISAR echo signal model and imaging mechanism of blind moving target are established with orthogonal frequency division multiplexing (OFDM) communication signal. Then, the fast imaging algorithm with wavenumber domain processed and tracking based on Kalman filter and Hungarian method for ISAC-ISAR blind moving target sensing are proposed, respective. Lastly, the ISAC real experiments are designed and processed based on universal software radio peripheral to demonstrate the performance and feasibility of the proposed method.
