Figure 7From: Developments in target micro-Doppler signatures analysis: radar imaging, ultrasound and through-the-wall radarFocused 94-GHz SAR images, each with five simulated targets vibrating at (Top) 30 Hz and (Bottom) 50 Hz. Vibration amplitudes from left to right are 10, 1, 0.1, 0.01, and 0.001 mm for both images [14].Back to article page
