Radar Measurement of Human Polarimetric Micro-Doppler

Abstract: We use polarimetric micro-Doppler for the detection of arm motion, especially for the classification of whether someone has their arms swinging and is thus unloaded. The arm is often bent at the elbow, providing a surface somewhat similar to a dihedral. This is distinct from the more planar surfaces of the body which allows us to isolate the signals of the arm (and knee). The dihedral produces a double bounce that can be seen in polarimetric radar data by measuring the phase difference between HH and VV. This … Show more

“…A multitude of works in the open literature have considered the use of multiple polarizations for a variety of applications, such as MIMO radar [7]- [11] , weather radar [12]- [14], or imaging radar [15]- [19], among others. More recently, the exploitation of such diversity has been considered for target classification based on the polarimetric micro-Doppler signature [20]- [23] as well as an effective way to improve the performance of passive radar systems [24]- [28].…”

“…Various campaigns have been undertaken to measure micro-Doppler characteristics via direct measurement [16], [17], [19], [21], [23], [25], [31], [32], [38]. A 94 GHz radar was used for measurements in [23] to obtain spectrograms for human motion detection.…”

“…Fully polarimetric radar data can potentially improve the separability of different parts of human motion. One of the techniques to determine whether people are carrying something in their arms is looking at their arm motion [84, 85]. The arm is often bent at the elbow, providing a surface similar to a dihedral, which creates a double bounce of the radar signal.…”
