Millimeter-wave (mmWave) Multiple-Input Multiple-Output (MIMO) radars have gained significant attention in recent years due to their unique capabilities. These radars employ MIMO technology for signal transmission and reception, enabling high-resolution imaging and precise environmental sensing.
In MIMO radar systems, including those using Frequency Modulated Continuous Wave (FMCW) techniques, enhancing spatial resolution without requiring a large number of transmitters and receivers is crucial. Common techniques for such radars include Time Division Multiplexing (TDM).
These radars offer several advantages, including effective operation in various weather conditions such as rain, fog and dust, as well as reliable performance under different lighting conditions, including day and night. They operate in frequency bands such as 24 GHz, 60 GHz and 79 GHz, making them suitable for a wide range of industrial and automotive applications.
Electromagnetics Infinity offers design, simulation, and manufacturing services for mmWave MIMO radars based on commercially available chipsets. Our process addresses every aspect of the complete radar system, from system architecture definition and antenna design for both transmission (Tx) and reception (Rx), to electromagnetic simulations, signal processing, integration of microcontroller units (MCUs) and digital signal processing (DSP) units for system control and functionality.
Below figure shows an example of near-field microwave imaging of metal objects using mmWave radar combined with advanced signal-processing techniques.
