Radar jamming will become much more complicated in future. The credit of this increase in the complexity of the radar signals goes to the research carried out by Mehul Malik and pals at the University of Rochester in New York. This new imaging system is based on the quantum properties of the photon.
A few of the various methods used to jam radar signals are:
- By overlapping the radar frequency with noise.
- Dropping chaffs (thin foil strips ejected into the air as a radar countermeasure) to create a false reflection.
But most of the modern radars can easily get past these artifices. So, to avoid detection by an enemy radar, a better approach would be:
To capture the incoming radar signals, modify them to give misleading information about the target and sending them back to the radar.
Malik and company have based their new technique on the quantum properties of the image. Of course it is possible to intercept these signals too but any attempt to change the information conveyed by the photons would result in the change in polarization of the photons.
Thus it is possible to detect the presence of a hostile object in the skies.
