We have reproduced MIMO-SAR using COTS single-chip mmWave radar and achieved a quite good imaging effect. We apply it to soil wetness detection and achieve a 100% binary classification.

Modified the commercial off-the-shelf device DWM 1002 Module to function as a tag with multiple antennas.

A UWB multipath triangulate localization algorithm is proposed and achieved , including the generation of UWB signal and the channel model, the extract of CIR, the obtainment of AOA, AOD, rTOF and the localization algorithm. The simulation is initially verified successfully.

In this paper, we present Radar-Immune, a novel parallel interference cancellation system. Radar-Immune leverages phase modulation of two chirp sequences, effectively distinguishing the interfering signal from the reflected signal in the Doppler domain. Additionally, we introduce an intersection algorithm to cancel parallel interference. We implement Radar-Immune and conduct performance evaluations for interference cancellation. Experimental results demonstrate an impressive interference cancellation rate of up to 97%.
