The Millimeter-Wave Radar MMW on Roi-Namur is the highest resolution, highest metric accuracy radar at the Reagan Test Site on Kwajalein Atoll in the Marshall Islands. Originally designed as a 1 GHz bandwidth Ka- and W-band adjunct to the Advanced Research Projects Agency Lincoln C-band Observables Radar, the original charter for MMW was to provide a database of millimeter-wave signature data of missile reentry phenomenology. MMW has been upgraded several times over nearly 30 years of operations in response to evolving missions and requirements. Most recently, a 4 GHz bandwidth capability 33.0 to 37.0 GHz was added that improves the radar image resolution to 6 cm, making MMW the highest-resolution coherent instrumentation radar in the world.
