Abstract :
An interferometric radar operating between 6 and 9 GHz for non-invasive measurement of the respiration rate, is presented. An adaptive RF front-end tracks slow body movements by changing the operating frequency such that the sensing system always operates in its optimum point. Experimental results have been obtained from human beings and the good correlation between the radar signals and a reference signal obtained from a conventional respiratory sensor show the validity of this approach.
