Doppler Radar
AFMCW86G40f is “FMCW based 86GHz-MIMO based Radar Engine”. This radar transmitting low power (+13dbm) and having small weight compact non rotating indoor radar for ranging application . License is not required to run or purchase or re-sale Radar Software is compatible with Windows 7 and higher versions .the echo raw data is sending to PC through USB 2.0 cable . Radar placed on Tripod with battery backup of 1 hours thus it is easily moved within the campus or Lab. Stationary & moving targets like drone , corner Reflectors are utilize during experimentation .before installation, necessary environments of lab also taken care like ESD floor mat , Non reflecting wall paper, Window curtains, Glass coating. Simple USB 2.0 radar PPI screen/ Output presented on 24inch LCD screen.The Radar is rapidly configure install with help of browser based API.The radar is configure in various way for different experiments and research activity .
- Measurements Target Range Vs Angle Using PPI Chart
- Multiple Target & Echo Observation Using PPI Chart

Benefit of Milli -Meter Wave Band in Radar?
RCS is the function of area of reflective surface available in front of Radar. Smaller wavelength is cable to attained smaller objects like blade of drone. Targets in motion relative to the radar cause the return signal frequency to be shifted. A Doppler shift only occurs when the relative velocity vector has a radial component. In general there will be both radial and tangential components to the velocity. Thus the wavelength is too small so that wider Doppler Shift & Wider Velocity of targets are detected so suitable for industrial applications.
