![]() So before we jump into some of the algorithms, we should talk about the configuration of the demo. Once the DSP has finished its processing, then the arm takes the resulting 3D point cloud that has been generated and transmits it to the UR- where the currently where the GUI is doing the state machine processing and display. This currently is running in the Matlab GUI. And it will eventually run the state machine tracker algorithm itself. The DSP runs the clutter removal, heatmap generation, CFAR, elevation estimation. This can roughly be divided into four pieces, the first part being the radar front end, which is collecting the samples, placing them into the ADC buffer the hardware accelerator doing the range processing, producing the radar cube the DSP, which then becomes active at the end of each chirping period. OK, for the signal processing chain, for an overview, this picture shows the high-level flow from the radar front end all the way to the output of our point cloud. We also have a video of this demo in action, which can be found at this URL. ![]() We provide a design document, which can be found by searching ti.com for TIDEP-01023. We provide full reference software, which is located in the TI Resource Explorer. And the demo is designed to detect four to five people in two rows and child presence detection anywhere in those two rows, including the footwell. In this current demo, our sensor is mounted on the roof. For in cabin usage, we have a field of view in elevation and azimuth that's roughly equivalent, which is 120 degrees, with a 29 degree resolution of the angle estimation. The benefits of the AOP device are a small form factor, reduced complexity for system design, reduced system cost, and higher efficiency compared to modules with other similar antennas. The antenna design is designed to provide an equal resolution in both azimuth and elevation and a good angle estimation accuracy. This gives us a total package size of 15 millimeters square. OK, for the AOP overview, the AOP 60Ghz is an antenna on package technology, which means that the transmit and receive antennas are printed directly on the surface of the package itself. ![]() And then where those algorithms have deviated from the typical use, we will describe what those changes are. We will talk about the algorithms themselves. ![]() And then we will go through the overhead VOD algorithms. In the first part of this training, we will give a brief overview of the 6843AOP. This demo was designed to run on 6843AOP and ODS 60GHz radar devices. Welcome to the two-part deep dive training for the overhead vehicle occupancy demo. ![]()
