Application of radar technology for contactless detection and monitoring of respiratory and heartbeat activity are known since 1970-s. Its operation principle relies on the fact that an electromagnetic wave reflected by a periodically moving surface is characterized by a phase modulation which may be cause by respiration movements, heart muscle contractions, etc. Nowadays bioradar devices become promising tools in a few areas of applications such as military, security, and healthcare. It may be also employed in pharmacology and zoo-psychology when studying new medicines or conducting behavioral tests for measuring the loco-motor activity of animals. The goal of the present work is to investigate the feasibility of bioradars usage for monitoring the respiration pattern of sleeping animals. Application of the method may be convenient for recording the respiration pattern while testing new technical and pharmacological approaches for treating sleep breathing disorders. Now, invasive and contact methods are used to control the physiological parameters of laboratory animals. The main drawback of invasive methods is the high workload and time consumption because of the necessity to implant electrodes. Contact methods are less harmful for an animal than invasive ones, but such methods provide reliable results only when the animal motion is restrained. Thus, a contactless and cheap method for prolonged monitoring of different types of animal respiration pattern is an up-to-date task of biomedical engineering.
