Signal Intelligence: Automatic Carrier Detection with an Instantaneous Bandwidth of 27 MHz

The control of the electromagnetic spectrum is of great importance to guarantee military operations, communication of the civil population, strategic government communication, among others. The main difficulty to have a control and guarantee a use according to the norms of each country of the spectrum, is in the high cost of the control equipment and the need for permanent operators to process the information of these sensors. In the present work, a low-cost automatic carrier detection system is proposed, which allows deploying a greater number of sensors and with automatic detection automatically emit alerts in case of use of restricted frequencies. This facilitates the control of the spectrum, especially of critical bands for military operations, being the first step to maintain the sovereignty of the spectrum.
