With another year coming to a close, The Modern Battlespace team takes this time to reflect back on lessons learned and important insights shared across the defense community that contribute to the progress of the battlespace as we know it. An important focus for the defense community this year is software defined radios SDRs , pointing towards an overarching trend of modularity and open systems on the battlefield. Here are a few compelling thoughts from different experts about SDRs and their growing role in the military:. In , the market was growing at a steady rate and with the rising adoption of strategies by key players, the market is expected to rise over the projected horizon. In a recently published byline on The Modern Battlespace , Dr.

Have you dipped your toe into the SDR ocean? While hacker software-defined radio has been a hot topic for years now, it can be a little daunting to try it out for the first time. SDR breaks out of that by moving to a piece of radio hardware that can be reconfigured to work with protocols merely by making changes to the software that controls it. This makes the radio hardware more expensive, but also means you can listen and sometimes transmit to a wide range of devices like that wireless doorbell or automotive tire pressure sensors, but also radio-based infrastructure like airplane transponders and weather satellites.
Software-defined radio SDR is a radio communication system where components that have been traditionally implemented in hardware e. A basic SDR system may consist of a personal computer equipped with a sound card , or other analog-to-digital converter , preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware electronic circuits. Such a design produces a radio which can receive and transmit widely different radio protocols sometimes referred to as waveforms based solely on the software used. Software radios have significant utility for the military and cell phone services, both of which must serve a wide variety of changing radio protocols in real time.
The product can be used as both a transmitter and a receiver for a variety of real-world applications. Here is our table of the best software-defined radios for Below we have also reviewed each of our top picks and outlined our research methodology. Read our review. It has both a transmitter and a receiver to enable true standalone operation as a radio system.
