Research into Vital Sign Target Imaging Algorithm Based on Range Doppler Two-dimensional Sparse Reconstruction
In the field of signal detection of human vital sign,non-contact vital sign radar uses the micro-Doppler information generated by the human chest cavity during breathing for imaging and detection,and has been more and more widely used in medical treatment,emergency rescue,indoor detection and so on.In such scenes,there are mostly moving objects interfering with the target and affecting the detection of human target vital sign signal.The two-dimensional sparse reconstruction image algorithm based on range Doppler is studied,and the two-dimensional spatial imaging and positioning of human targets are completed under the condition of suppressing the interference of moving objects.
