77 GHz Automotive Safety mmWave Radar Obstacle Sensor

Millimeter-Wave-Radar-sensor

 

Model No.: SRR-10

 

INTRODUCE:

77 GHz Millimeter wave automotive safety radar, SSR-10 is the new generation short range wideband, high resolution automotive radar sensor built with customizable cutting edge radar technologies. It is built on Millimeter wave technology allowing for ultra low power consumption and low unit cost. The sensor’s highly integrated hardware, advanced radar signal processing algorithms enable 360 surround high resolution detection when multiple units configured on the vehicle, and allow semi-autonomous or fully autonomous driving.

The ultra high range resolution, faster update rates, CAN-FD data link options make it a great solution to implement sensor fusion for ADAS and self-driving applications.

These millimeter wave radar sensors provide an ideal solution for low-power, self-monitored, ultra-accurate radar systems in industrial applications, such as building automation, factory automation, drones, material handling, traffic monitoring, and surveillance.

APPLICATIONS

 

  • Large vehicle parking sensor
  • Forward collision warning
  • Headway monitoring warning
  • Automatic emergency braking
  • Pedestrian and cyclist collision
  • Adaptive cruise control

Multi-target tracking: 32 targets can be tracked simultaneously in the beam range;

Communication interface: CAN interface rate 500K; serial port baud rate 115200;

Data calibration: Data is calibrated by CAN and stored, and it takes effect after restarting the power supply; Firmware upgrade: free to disassemble, upgrade firmware through CAN interface, take effect after restarting power supply.

 

CAN transmission protocol:

The CAN bus interface supports target information output, data calibration, firmware upgrade; the CAN bus communication network conforms to the ISO11898-2 standard, and the transmission rate is 500K bits/second, frame type is 29-bit extended frame ID.

ID calculation:

Radar message ID = radar ID * 0x10 + base message ID;

CAN bus can mount up to 16 devices, each device has its own ID;

When the radar ID in the above table defaults to 0, the basic message ID is 0x40B, 0x200 , 0x201, 0x700, 0x701;

If the radar ID is configured to 1, its message ID is 0x41B, 0x210, 0x211, 0x710, 0x711, and so on.

 

Target Information:

The target information is sent through the ObjectInfor message frame, and the base message ID = 0x40B;

Serial transmission protocol:

 

The radar module uses 3.3V TTL level output by default. It can be external TTL to 232 module or other communication interface compatible with the current host hardware. The baud rate is 115200, and the data is output by string.

-The first string represents the number of targets detected by the current frame.

-The second string represents the target number detected by the current frame.

-The third string represents the X-axis lateral coordinate (in m) of the current target.

-The fourth string represents the Y-axis longitudinal coordinate (in m) of the current target.

-The fifth string represents the Y-axis longitudinal velocity (in m/s) of the current target.

The strings are separated by spaces, and the data between different target numbers is distinguished by the line feed \n;

 

Examples of receiving data are as follows:

2 0 -1.33 7.11 0.01

2 1 -0.06 1.92 0.00

This part of the data indicates:

2 targets were detected,

No. 0 The target is located at -1.33m in the horizontal direction, 7.11m in the longitudinal direction, and the longitudinal velocity is 0.01m/s;

No. 1 The target is located at -0.06m in the horizontal direction, 1.92m in the longitudinal direction, and the longitudinal velocity is 0.00m/s.

Appearance:

With the ruggedized design and the considerations for industrial and specialty vehicles, SRR-10 automotive radar sensors can be strategically placed on the exterior of the vehicle and deliver the superior performance in all tough working environment.

Millimeter Wave Radar Sensor Test Tools:

This Test demo is for SRR-10 radar sensors test based on Windows OS. Connect with PC for testing, there are CAN tools needed in the sensor and PC connection, typical CAN tools is CANalyst-II and USB-CAN-2EU. For sample order, we normally offer 1 of CANalyst-II tools for user easier conect and test.
