Radar is important on the battlefield but has a few problems in areas of high radio traffic density. Now the researchers have developed an adaptable, noise-encrypted radar waveform called Advanced Pulse Compression Noise (APCN). The technology combines aspects from both traditional and non-traditional radar systems, and can be tuned in real-time to allow system users to adjust radar performance depending on their surroundings.
Paul Zablocky, director of intelligence and information warfare at the US army’s Communications-Electronics Research, Development and Engineering Centre (CERDEC) said that techniques such as real-time re-programmable waveform synthesis and low probability of intercept/low probability of detection (LPI/LPD) provide added capability that will address the emerging electromagnetic spectrum challenges our soldiers are likely to face in the future.
The tech was patented by research scientist, Mark Govoni, and he said that it used encryption. Encrypted radar waveforms would help limit the likelihood of enemies intercepting and exploiting communications.
The secure waveform could also be applied outside of the military by civilian law enforcement. The radar waveform is continually changing and never repeats itself. It looks like noise and is extremely difficult to intercept. Coppers using one are anonymous to radar detectors.
