Figure 3From: Developments in target micro-Doppler signatures analysis: radar imaging, ultrasound and through-the-wall radarTime frequency signature of oscillating reflector [15] analysed using the AOK method showing a feature oscillating between 70 and 85 Hz with a 2.5 Hz oscillation peak-to-peak with a 0.5 s of periods. These values links to the ground truth.Back to article page
