With more as well as more vehicles driving themselves, there is an increasing demand for precise atmosphere conscious sensors. From collision avoidance to smooth driving, environmental understanding is a must have for any type of self-driving cars. go into automotive radar: cool, precise as well as fairly cheap. thanks to a contributed automotive radar module, [Shahriar] gifts us with a “tutorial, experiment as well as teardown.”

Before digging into the PCB, [Shahriar] explains the theory. With just sufficient math for the mathmagically inclined as well as not as well much for the math adverse, [Shahriar] goes into the details of exactly how automotive radar is different from typical stationary radar.

Only after a short overview of the Doppler effect, [Shahriar] digs into the PCB which exposes three die-on-PCB ASICs accountable for generating as well as getting 77GHz FMCW signals coupled to a 2D array of antennas. Moreover, [Shahriar] explains the a number of microwave elements such as “rat-race couplers” as well as “branchline couplers.” Additionally, [Shahriar] shows off his awesome PCB rulers from SV1AFN style lab that he utilizes as a recommendation for these microwave components. Finally, a physical embodiment of the Doppler impact radar is demonstrated with a pair of Vivaldi horn antennas as well as a copper sheet.

We truly like exactly how [Shahriar] structures his video: theory, complied with by a teardown as well as then a physical experiment to drive his lesson home. If he didn’t already have a job, we’d state he may want to think about teaching. If the video after the break isn’t sufficient radar for the day, we’ve got you covered.
