Claim:
1. A method for adaptive Radio Frequency (RF) communications, the method comprising: transmitting a data pulse in a RF spectrum, wherein the data pulse is modulated with data; and after transmitting the data pulse, transmitting a reference pulse separated by a predetermined period of time from the data pulse, wherein the reference pulse is unmodulated but otherwise identical to the data pulse, wherein the reference pulse is configured to serve as a correlation template for the data pulse; dynamically monitoring the RF spectrum; detecting any undesired signals in real time from the RF spectrum; and sending directional countermeasure signals to jam the undesired signals simultaneously, wherein the directional countermeasure signals are adaptively generated in real-time according to a bandwidth of the undesired signals; wherein the bandwidth is in a range from a narrow bandwidth to an ultra-wide bandwidth (UWB) to cover a very wide range of frequencies to jam many interferers at once; and wherein the directional countermeasure signals are sent by an antenna that directs the countermeasure signals towards a source of the undesired signals without interfering with friendly communication devices sending desired signals.
