Real-time 2D+velocity localization measurement of a simultaneous-transmit OFDM MIMO Radar using Software Defined Radios

For the first time, real-time 2-Dimensional localization and velocity measurements using simultaneous 4×4 transmit and receive antenna configuration with an OFDM Radar implemented on commercially available Software Defined Radios (SDR) are presented. The Radar setup uses 100MHz bandwidth at 4.05 GHz to achieve a range resolution of 1.5 m, and the integration time of 11.8 ms to obtain a velocity resolution of 22.6 km/h. All Radar parameters were chosen based on the limits of the SDR. This real-time capable measurement setup aims to enable further research and rapid-prototyping of MIMO Radars for use in various applications especially in area surveillance and drone detection.
