Abstract
A method of transmitting a message using a slow hopping anti-jam waveform, includes generating a sequence with a cryptographic hash function; transmitting, for a predetermined dwell time, a first portion of the message on a first channel having a first baseline frequency; choosing a second channel having a second baseline frequency based on the generated sequence, the second baseline frequency being offset from the first baseline frequency; and transmitting, for the predetermined dwell time, a second portion of the message on the second channel having the second baseline frequency; wherein the two transmitting steps occur sequentially.
