Requirements for Radar System for automotives for ADAS applications
Why Radar? The radar sensor detects objects and measures their relative velocity and position. For that purpose, the sensor has four antenna elements that simultaneously transmit radar waves in the frequency range between 76 and 77 GHz. These waves are reflected by objects. By comparing the amplitudes and phases of the signal echo received by the antenna elements, precise conclusions on the objects’ position can be drawn. The relative speed and distance of objects is measured using Doppler Effect (shift in frequency between the reflected and transmitted signals) and time lag. The radar sensor can be applied to a series of functions which can also be accomplished parallell. By the identification of objects in the driveway the radar sensor is able to measure the distance and the relative speed of these objects. The subsequent object classification in relevant and non-relevant barriers enables the recognition of critical situations. The radar enables the realization of an intelli
mmwave sensing Lecture 2: The Phase of the IF Signal
Can you refer a source to help decide an optimum oscillator phase noise for a synthesizer so that a desired IF signal of a particular receiver sensitivity can be detected?
ReplyDeletesure, i'll get back to you asap. sorry for the delayed response.
DeleteIndeed you have delivered excellent lectures. But if you demonstrate it with MATLAB codes, it will add more sugar to it. Regards
