Abstract
Radar echo signal through wall detecting is a kind of new exploring life technology used for seeking wounded personnel on the ruin of earthquake and rescuing hostages from terrorists. The attenuation of radar wave after penetrating wall and the wavelength selecting were summarized, radar echo signal was theoretically deduced, Bessel function was introduced into processing echo signal and the basic frequencies and harmonic combinations of breathing and heart beating were simulated. The simulation result is consistent with the theoretical analysis.
