| Abstract: |
Our proposal specifically addresses the stated requirements of the solicitation; we will develop and deploy tools and methods for efficiently collecting, analyzing and classifying narrowband signals within a wide radio-frequency spectrum. The number of potential hostile waveforms in the RF environment will continue to increase with an essentially random distribution. However, at any given time, the overall spectrum population is sparse. Any receiver on an airborne platform attempting to perform SIGNAL Intelligence (SIGINT), or Communications Intelligence (COMINT) currently relies on brute-force Nyquist sampling of wide swaths of spectrum and using storage and processing-intensive methods. The approach we propose aims to reduce the processing, storage, and transmission burden on the SIGINT system by using innovative sampling techniques and algorithms as well as making better choices about where in the spectrum to focus the search for signals of interest. The proposed Edaptive Heiste solution builds on previous Edaptive Computing, Inc (ECI) knowledge and technology - itself innovative - to provide the user with near real-time intelligence of the various communication signals in the vicinity. The proposed solution will add to the situational awareness of the war-fighter and do so in a manner that does not demand vast hardware and processing resources. |
| Benefits: |
Airborne data collection platforms such as E-2 Hawkeye and Broad Area Maritime Surveillance (BAMS) serve as early warning and command/control relays for the military. They scan vast geographic and RF space and generate large amounts of sampled data for storage and transmission to a ground or ship-based station. As more adversarial nation-states and organizations gain access to ever-cheaper communications technology, the total number of potential hostile waveforms in the RF environment will continue to increase. However, the instantaneous spectrum picture is generally sparse and this observation will be exploited in our solution.
The traditional Nyquist sampling approach necessitates sampling rates in the multi-GHz range, leading to enormous processing, storage and transmission requirements for airborne platforms attempting to perform SIGINT/COMINT. The approach we propose aims to reduce this burden by taking advantage of spectrum sparsity, using innovative sampling techniques and algorithms as well as making better choices about where in the spectrum to focus the search for signals of interest. This will lead to a reduction in the amount of data that must then be transmitted over-the-air (OTA) to the collection point. Such a solution will naturally reduce the Size, Weight and Power (SWaP) budget of SIGINT/COMINT systems with all the additional benefits this entails.
It is anticipated that this approach will also be of great benefit to emergency communication networks as well as commercial cognitive radio networks, indeed, any domain where there is a requirement for extremely high sampling and data transmission rates.
