Radar Cross Section

« Back to Glossary Index

The Radar Cross Section is a measure of the effect a physical presence will have on radar waves. When a radar wave hits a target it is scattered or reflected and this effect on the wave is measured by the receiver. A target’s ability to scatter or reflect the wave is known as the target’s Radar Cross Section and is determined by a range of factors including size, weight, material, density etc. In Sensurity’s products, the measurement recorded by the receiver is compared to the information held on a wide number of targets’ Radar Cross Section. This comparison is then used to determine the Radar Cross Section of the target, and from there determine whether the target is in fact a human, vehicle or a non-intrusion event.
