The Ainstein T-79 is designed for Advanced Driver Assistance Systems (ADAS) applications, like warning or assisted braking functions, blind spot monitoring, lane change assist and rear crossing traffic alerts.
It is based on 79GHz technology and contains six planar antennas, four for reception and two for transmission. The sensor has a field of view of ±45° in azimuth and a maximum range of 55m.
Resulting from a collaboration with Texas Instruments (TI), the system integrates only one electronic board, equipped with a TI CMOS single-chip millimeter wave (mmWave) sensor. This monolithic microwave integrated circuit (MMIC) features six channels, again that’s four receivers and two transmitters, along with a microcontroller unit (MCU) and a digital signal processor (DSP) all on the same chip. The enables ultra-low unit cost and power consumption of 4.2W.
The electronic board is manufactured with an asymmetric structure using a hybrid PTFE/FR4 substrate, and is equipped with planar antennas.
With this new short-range radar generation, Ainstein has significantly decreased the volume and manufacturing cost of the sensor compared to competitor solutions. The report contains a comparison with Delphi’s 76/77GHz Blind Spot Radar.
Based on a complete teardown analysis of the Ainstein radar, this report provides the bill-of-material (BOM) and the manufacturing cost of the radar sensor.
