Advanced ECCM Technology (ANTI JAMMING)

A novel narrowband modulation offering low probability of exploitation ( LPE, a measure of information security ) and anti jamming for high data rate transmissions. Unlike the conventional LPE and AJ modulation such as direct sequence spread spectrum or frequency hopping which occupy a very wide spectrum, PPH does the hopping in polarization domain, thus occupying a very narrow spectrum. This feature makes PPH the only choice for high data transmissions with LPE and AJ security feature over bandwidth constrained channels.
