SkyRadar FMCW Base Module
New call-to-action

FMCW Base Module

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. 

General Features

  • Active radar, designed for perfectly save indoors and outside operation in close and near range (transmitter output power significantly lower as such of a mobile phone)
  • The following operating modes can be technically enabled in the hardwarestativ_kmc1_cut.png
    o   FMCW
    o   Doppler
  • Antenna
    o   Standard: Horn Antenna , Extended / Extreme / Superhet: Array Antenna
    o   Default operation 24 GHz
  • Powerful and fast radar image processor.
  • All measurements are performed in near-to real time. No sub‐sampling or substitution techniques.
  • Optimized for detection of real targets in a 3-dimensional space within laboratories or outside , remote controlled remote controlled aircrafts. No limiting target table or rail system required.
  • Extendable with rotary tripod, parabolic reflector, linear conveyor for SAR operations
