Abstract
Systems and methods for reprogramming a Single Channel Ground and Airborne Radio System (SINCGARS) having a SINCGARS frequency-hopping waveform with a fixed retuning period operable in a network of SINCGARS. A system includes a controller programmed with a modified frequency-hopping waveform having one or more retuning periods, each of the one or more retuning periods being shorter in duration than the fixed retuning period of the conventional SINCGARS waveform, the modified frequency-hopping waveform compatible with each of the SINCGARS in the network. An interface is provided for programming each of the devices with the modified waveform.

In a Single Channel Ground and Airborne Radio System (SINCGARS) having a SINCGARS frequency-hopping waveform with a fixed retuning period operable in a network of SINCGARS, a system comprising:
- a) a controller programmed with a modified frequency-hopping waveform having one or more retuning periods, each of said one or more retuning periods being shorter in duration than the fixed retuning period of the conventional SINCGARS waveform, said modified frequency-hopping waveform compatible with each of the SINCGARS in the network;
- and
- b) an interface for programming each of the devices with the modified waveform.
A system for improving radio frequency (RF) frequency-hopping in a network of devices configured with an original waveform having fixed retuning period, the system comprising:
- a) a controller programmed with a modified frequency-hopping waveform having one or more modified retuning periods compatible with each of the devices in the network, each of the modified retuning periods shorter in duration than the fixed retuning period of the original waveform;
- b) an interface for programming each of the devices with the modified waveform.
A method for improving radio frequency (RF) frequency-hopping in a network of devices configured with a waveform having a fixed retuning period, the method comprising:
- a) assembling a network of RF frequency-hopping devices, configured with an original waveform having a fixed returning period;
- and,
- b) reprogramming the frequency-hopping devices with a modified waveform having a retuning period shorter in duration than the fixed retuning period of the original waveform.
A method comprising:
- a) assembling a network of radio frequency (RF) frequency-hopping devices in a network of devices configured with an original string of multiple waveforms, wherein each waveform operates on a distinct frequency and comprises a fixed retuning period and a dwell period;
- and
- b) reprogramming the frequency-hopping devices with a modified string of waveforms, wherein generating the modified string of waveforms comprising:
- i. dividing each waveform of the original string into two or more sub-hops, wherein each sub-hop includes a portion of the fixed retuning period and a portion of the dwell period, and
- ii. interleaving each sub-hop such that sub-hops operating on a same frequency are time-dispersed.
A system comprising:
- a) a network of radio frequency (RF) frequency-hopping devices in a network of devices configured with an original string of multiple waveforms, wherein each waveform operates on a distinct frequency and comprises a fixed retuning period and a dwell period;
- and
- b) a controller configured to reprogram the frequency-hopping devices with a modified string of waveforms, wherein the controller generates the modified string of waveforms by:
- i. dividing each waveform of the original string into two or more sub-hops, wherein each sub-hop includes a portion of the fixed retuning period and a portion of the dwell period, and
- ii. interleaving each sub-hop such that sub-hops operating on a same frequency are time-dispersed.
