The Radio Array of Portable Interferometric Detectors (RAPID) is being designed for investigations of ionospheric phenomena, solar radio emission, the Galactic synchrotron background, and ultra-high energy cosmic rays via airshower emission. The array will consist of 50-100 small, low-gain broadband antennas operating below 500 MHz. Unlike existing arrays, RAPID can be operated without any cabling between the antennas and a central location, and can be shipped, deployed and physically reconfigured quickly and easily with zero site infrastructure.
