Biological Radar is a special radar used to detect life forms , it combines radar technology and biomedical engineering in one life forms do not require any contact with the electrodes or sensors interval distance , penetrate nonmetal medium ( brick walls , ruins , etc.) to detect life the life of the body ( the body ) signal ( breathing , body movement , etc.) , the technology in wartime and peacetime , a wide range of applications , such as military medicine ( casualty search and rescue ) , disaster Medicine ( earthquakes or landslides wounded explore ) and other fields . In the above - mentioned applications not only concerned about whether the probe to the target ( human ) survival , but also concerned about the status of the target , such as the type of the target , the number of distance information . Continuous wave of biological radar developed by our team , has to solve the target the computer smart discriminant survival , but failed to effectively solve the two major problems exist : 1 , computer recognition of the target information , these information include the type of the target ( human or animal ), the number of targets ( single or multiplayer ), etc.; 2 , the detection of the target distance information . This study is based on the following aspects of the work to the above two questions : 1 , collected target information related to the experimental data ( the breathing signal ) between man and animal , single and multiplayer conditions , power spectrum estimation and spectrum transform the target signal characteristics of these experimental data analysis to identify different target , the difference between the signal characteristics of the different number of conditions for the same goal , to provide data for computer identification of the target information ;
