The PSR base unit of the SkyRadar Modular Radar Training System in an extension of the NextGen Radar Training system. It is based on a noise radar. Technically, the SkyRadar Base Module is based on a pulsed noise radar. It is operatable in Doppler and Pulse mode. The SkyRadar Base Module allows for experiments ranging from basic working principles like validating the radar equation to most complex radar scenarios. The system operates with the SkyRadar FreeScopes Software which provides many scopes (A-Scopes, B-Scopes, PPI), control interfaces and filters. The module allows for highest flexibility in the learning process, while providing high-resolution at close distance with an electro-magnetic emission of a small fraction of that of a mobile phone. ​​
