This project validates whether a given string follows specific movement rules within a 4x4 character matrix. The string is valid if: Each character exists in the 2D array. Each character in the string ...

Abstract: Compared to conventional 3D radar systems, 4D radar systems require higher angular resolution in both azimuth and elevation. Besides, sparse arrays offer several advantages, including ...

Abstract: In this paper, the problem of joint time-of-arrival and two-dimensional direction-of-arrival (TOA/2D-DOA) estimation is solved using space-frequency nested array (SFNA) motion. SFNA is ...
