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. The radar source is traditionally an FMCW radar. In reality these images are created by side-lobe radars of aircrafts. SkyRadar's SAR add-on extends the FMCW 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 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.
The SAR Module is an extension of the FMCW base module. A step-motor-controlled linear axis allows movement of the transceiver and antenna and thus produces radar images with defined time-stamps and positions for SAR operations. SAR aggregates the data in a time-multiplex approach. SAR allows producing resolutions which go far beyond results of a normal antenna.
To run iSAR, the system requires the Mobile Target Positioning System to rotate the target.
The FMCW Base Module can be applied to experiment on the following subjects (selection):
The SAR Module consists of:
The SkyRadar SAR and FMCW Base Module is accessible by an unlimited amount of concurrent users. The broad coverage of solutions useful in ICAO and EuroControl ATCO and ATSEP training programs as well as IATA qualifications make SkyRadar the preferred choice of many aviation academies and IATA TrainAir Plus accredited institutions. Many universities and military academies use the PSR Base Module within their qualification, education, training or research programs.
