Specifications / Features

Silicon Radar’s MIMO evaluation kit is a fully embedded system providing the user with a number of methods for visualizing and working with MIMO radar data through the use of a GUI. This gives the user an ability to change a number of system parameters and see the resulting system performance.

Data Visualization

The two primary data views are Range – Doppler (plotting distance against speed data, shown left in figure above) and Range – Azimuth (plotting range against angular data, shown right in figure above) heat maps. By default they appear as shown in the figure above, but the user has additional options:

  • Clicking and dragging anywhere on the heat map will change its perspective and allow the user view a 3D representation of the heat map.
  • Choosing appropriate option in the dialog box below each heat map allows the user to view individual slices along Range, Doppler or Azimuth axis.

The kit processes all displayed information on kit, needing very little resources from a user’s machine and achieves a minimum update rate of approximately 10Hz.

The GUI also provides a status window giving up-to-date system information to a user based on the current system setup. Vital information including the resolution of range, azimuth and doppler estimation and other performance statistics are reflected there.

Finally if target detection is applied, any targets that meet the target detection parameters will appear in the target list. Each target is numbered and displayed with its associated speed, range and azimuth in a target list, placed in the bottom right of the GUI.

Adjustable System Parameters

Using the GUI the user can has the ability to adjust a great number of system parameters Using the GUI the user can has the ability to adjust a great number of system parameters

  • RF Parameters
    • Central Frequency between 22GHz - 26GHz,
    • Bandwidth selectable from 500MHz - 4GHz
    • Pulse Repetition Frequency selectable from 60Hz – 2200Hz
    • Adjustable Receiver Gain.
  • Range – Doppler Parameters
    • Choice of Maximum Range, Minimum Range selectable to limit the field of view.
    • Integration Time, Zero Padding and Windowing Function.
    • Achievable range resolution of at least 7.5cm.
  • Range – Azimuth Parameters
    • Maximum Azimuth, Minimum Azimuth selectable to limit the field of view.
    • Selectable Azimuth Estimation Algorithm.
    • Achievable angular resolution of at least 0.75 degrees.


Signal Processing

The Kit implements a number of signal processing algorithms for user evaluation. In windowing data the user can select between Rectangular, Hamming and Blackman functions.

The user is also provided with the choice angular estimation algorithms. Classical Beamforming is implemented as well as more computationally intensive subspace methods of MUSIC and CAPON algorithms to illustrate the relative performance of traditional methods with the improvements possible through greater computational resources.

The option to apply CFAR-based target detection to the heat map data is also implemented on the Kit with selectable CFAR mode, false alarm probability, guard cells, reference cells and dilation bins. Of the CFAR modes implemented on the kit, the user can select any one of Call Averaging (CA), Smallest of CA, Greatest of CA or Ordered Statistical CFAR. All targets detected according to the user setting get collated to a target list which can be exported separately
