A synthetic aperture radar is a radar which produces radar images of higher resolution than normal radars through the shooting of a series of radar images of the same target but from spatially displaced positions.  In real life these images are created by side-lobe radars of aircrafts. SkyRadar's SAR add-on extends the radar through a controlled linear axis and imaging logic - making it work like a side-lobe radar.

The iSAR solution uses the same imaging logic but builds on a fixed source and a rotating target (placed on SkyRadar's target positionning system).

The system operates with the NextGen 8 GHz Pulse Radar 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.
