Radars offer several important advantages compared to optical sensing technologies. They can operate reliably under challenging environmental conditions including rain, fog, dust and low-visibility environments, while maintaining stable performance during both day and night operation.
Millimeter-wave (mmWave) Multiple-Input Multiple-Output (MIMO) radars have gained significant attention in recent years due to their capabilities in detection, tracking and environmental sensing applications. By combining multiple transmitters and receivers with advanced signal processing techniques, modern mmWave radar systems, including Frequency Modulated Continuous Wave (FMCW) radars, enable accurate estimation of target range, velocity and angle. Techniques such as Time Division Multiplexing (TDM) MIMO are commonly used to increase the virtual aperture size and improve the angular resolution of the radar system.
Electromagnetics Infinity provides design, simulation and manufacturing services for mmWave MIMO radar systems operating in the 60 GHz and 79 GHz frequency bands and based on commercially available Texas Instruments chipsets. The development process includes radar system architecture definition, Tx and Rx antenna design, electromagnetic simulations, RF and hardware design, radar signal processing and integration of MCUs and DSP units for radar control and operation.
Below figure shows an example of near-field microwave imaging of metal objects using mmWave radar combined with advanced signal-processing techniques.
