At the heart of the system is an FMCW transceiver. A variable trigger wave allows to generate also a Frequency Shift Key Mode. In addition, the transceiver can operate in Doppler mode. The transmitter can emit very short pulses through the antenna and monitor the reflected pulses. The pulses are reflected of fixed objects (buildings, trees…) and moving objects (cars, people…) which pass the antenna beam. The FMCW Base Module provides the opportunity to study Doppler effects.
The signals are digitally processed using a Digital Signal Processor (DSP), data is visualized through the analysis and visualization software SkyRadar FreeScopes.
The system in its standard standard configuration has a range up to 50 m (detecting objects of the size of a car). The standard version comes with an array antenna.
