Company Information ........................................................................................................................ 1 Product Description The project ARS-ST01 is a multi-mode, FMCW radar sensor capable of operation in the 77GHz band. This radar sensor integrates the functions of two operation modes of SRR for long-range coverage and MRR for wide FoV coverage at near distance. It enables real-time detection of objects in front of the vehicle, collecting the information including range, relative velocity and azimuth of multi- targets, satisfying the ADAS demands for features like ACC, AEB, FCW in EV markets especially for electric bus. 2 Features ARS-ST01 adapted TI ARW1843 77GHz SoC Platform Support SRR/MRR dual-mode Max detection range up to 150m Detects moving vehicles Cost effective and robust design for all vehicle segments Immune to bad weather Programmable alert zones for customization Platform support ISO26262 ASIL-B function safety compliance 3 Specification Radar Specification Parameter Front Radar Unit Radar Characteristics Frequency Band 76 ~ 77 GHz Power supply 9-16 V DC Detection range 150 m Speed measurement range Field of view 90 H = ±3 / V = ±3 @150M km/h deg Distance measurement accuracy Speed measurement accuracy Angle measurement accuracy Emitted radar power (EIRP Peak) Emitted radar power (EIRP Average) <1.25 1.5 1.5 FCC : SRR:29.10 MRR:34.28 NCC : SRR:20.40 MRR:30.51 FCC : SRR:10.04 MRR:12.74 NCC : SRR:12.58 MRR:14.26 m km/h deg dBm dBm Update time 150 ms Normal power consumption Vehicle interface 10 W CAN Mechanical size (w/ connector) Weight 110 (L) x 66.1(W) x 15.8(H) mm 96 g Temperature range Operating: -40 ~ +85 °C Storage: -40~90 °C Mounting area Connector vertically: between 80~100cm above road surface level (35 degree) 10-pin female (socket) flat connector Vehicle integration Front (central) side of vehicle IP Rating IP69K Reliability ISO 16750 Regulation/ Certification Compliant Modulation-related technical parameters FCC, NCC Modulation period Modulation Bandwidth SRR: 76.10~76.78 MRR:76.10~76.34 SRR: 680 (total) MRR: 243 (total) GHz MHz Modulation Type Sweep Bandwidth Sweep Rate Sweep Time Maximum power modes (FCC) Minimum power modes (FCC) Power duty cycle (FCC) sawtooth SRR: 680 (total) MRR: 243 (total) SRR: 100 MRR: 100 SRR: 29.2 MRR: 22.2 SRR: 29.10 MRR: 34.28 SRR: 29.10 MRR: 34.28 SRR: 1.8 MRR: 2.18 MHz ms us dBm dBm % 4 Product Dimension The ARS-ST01 product dimension is 110 (L) x 66.1(W) x 15.8(H) mm (with connector) Radar front side view Radar side view Radar rear side view 5 Radar Setup Installation Height: The preferred installation height is 80~100cm. If the height is too low, the signal may be affected by the reflection of the ground due to the static object detection function. If the height is too high, the object reflection will be poor, which will affect the radar detection performance. Mounting Angle: Radar mounting angle should form a perpendicular line to the ground. Installation Precautions: There should be no metal objects within 80cm in front of the radar, it is also recommended that there should be no plastic object thicker than the radar to be placed in front of the radar, or false reading may occur. There should be no objects or body structures higher than the radar above and below the radar. The radar should be secured fasten on to the car body to avoid vibrations related to the radar and the car body. 6 Regulations 6.1 FCC Warning Statement FCC 15b devices (15.105) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. FCC Part 15.21 information for user You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment. FCC Part 15.19 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation FCC RF Radiation Exposure Statement 1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 2. This equipment complies with RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated, keeping the radiator at least 20cm or more away from the person's body. 6.2 NCC Warning Statement / NCC LP0002 _3.8.2 7 Company Information Alpha Networks Inc.
