Bioradiolocation is a method for detection and diagnostic monitoring of humans, even behind obstacles, by means of radar. It is based on the reflected signal modulation caused by movements of the body surface and internals. Objects of the human's body, subjected to more or less periodic fluctuations are:
  • Lungs (range of frequencies from 0.1 to 0.6 Hz)
  • Cardiac muscle (range of frequencies from 0.7 to 2.5 Hz)
  • Vocal organs (articulation)
  • Movements of other parts of the body.

We offer BioRASCAN-4 (4 GHz) and BioRASCAN-14 (14 GHz) bioradars.
