## Abstract

This project addresses the growing demand for high-performance, compact, and energy-efficient wireless systems by advancing Dual Function Radar Communication technology. DFRC systems integrate communication and sensing capabilities into a single platform, reducing hardware redundancy, cost, and power consumption while enhancing spectral efficiency. The research is aimed at next-generation applications — including autonomous vehicles, satellite and UAV systems, and smart manufacturing — where both high-speed communication and high-resolution sensing are critical. The project tackles key challenges in these domains, particularly the efficient allocation of spectral resources and the mitigation of Doppler-induced performance degradation in high-mobility environments where traditional systems fall short.

A novel Dual-Function Radar-Communication system is proposed to support high-mobility scenarios while efficiently utilizing bandwidth for both communication and sensing. The system features a monostatic multiple-input multiple-output (MIMO) radar that transmits OTFS waveforms. Bandwidth efficiency is achieved by enabling Doppler-delay domain bins to be shared across transmit antennas. A low-complexity approach is introduced to obtain coarse target estimates within the aperture limits of the receive array. This research further leverages a key strength of MIMO radar: achieving spatial resolution beyond the receive array’s aperture through the use of a virtual array. Forming a v
