AWR1243 Cascade (Rev. A)
This application report describes TI’s cascaded mmWave radar system. This solution is based on TI’s AWR1243 radar chip. Several of these chips are cascaded and operated in synchronism. Each AWR1243 chip supports up to four receive and three transmit antennas. Cascading multiple such chips allows the radar system to operate with more receive and transmit antennas, thereby improving target detection and resolution in comparison with a single AWR1243 radar chip based system. Cascading of two and four AWR1243 chips is illustrated in this application note, targeting automotive applications such as Adaptive Cruise Control, Collision Warning, Emergency Braking, and Semi and Fully Autonomous Driving.
