Spectrum Efficient National Surveillance Radar (SENSR): Overview of the “New MPAR”

The Multi-function Phased Array Radar (MPAR) initiative investigates the potential to combine the radar functions of several national radar networks and have them served by a single radar system delivering the required performance for aircraft and weather surveillance. Recent opportunities to acquire funds for development and potential acquisition of an MPAR-like system from proceeds of the sale of HF spectrum has led to interest in the MPAR concept as a possible solution. A new program called Spectrum Efficient National Surveillance Radar (SENSR) has been established as a collaboration between MPAR partners, the National Oceanic and Atmospheric Administration (NOAA) and the Federal Aviation Administration (FAA), and the defense/security community. This paper will provide an overview of the SENSR program, including its relationship with the former MPAR work and its schedule, opportunities, and risks.
