24GHz MIMO Radar Module Eval Kit

24GHz MIMO Radar module Evaluation Kit is a MIMO Radar module with Analog Devices MMICs ADF5901 24 GHz VCO and PGA with 2-Channel PA Output and ADF5904 4-Channel 24 GHz Receiver Downconverter. MIMO (Multi Input Multi Output) array antenna technology used in this module enables long-distance and wide-range azimuth detection, virtually increasing the number of Rx elements and improve the azimuth resolution.

Macnica's partner Sharp Takaya provides its signal processing technology for this module, enabling accurate detection of the angle and distance of the reflected wave and displaying the point with signal strength.

The derived signal data can be used to recognize objects such as people, cars, obstacles, etc. A sample radar display application software is included in the kit to show the strength of signals in a "heatmap" style scope.
