DualRAD60 Dual FMCW Radar Data 60GHz

The DualRAD60 dataset is based on the AWR6843ISK radar system, a MIMO FMCW radar from Texas Instruments. It operates at a center frequency of 60 GHz, with a frequency slope of 79.8 MHz per microsecond and a total bandwidth of 3.99 GHz. The system captures 128 ADC samples per chirp at a sampling rate of 11.648 MSa/s, and each radar frame consists of 32 chirps. The signal processing pipeline computes the range spectrum using a 128-point FFT along the fast-time axis and a 32-point FFT across the chirps to extract Doppler information. Static clutter removal mitigates interference from stationary objects. The radar transmits chirps with an idle time of 50 microseconds and an ADC valid start time of 7 microseconds, operating with a ramp time of 50 microseconds and a frequency sweep frame periodicity of 200 milliseconds.

 The DualRAD60 dataset comprises 3,038 measured Range-Doppler (RD) maps. Each RD map contains up to two randomly moving human targets in a parking garage. The measured dataset includes targets with diverse motion patterns, considering multipath propagation effects. The data is manually labeled to provide ground truth annotations, ensuring accurate evaluation and detection performance comparison.
