Radar systems aim for the detection, tracking, or imaging of objects. The automotive radar system studied in this project has the goal of detecting potential obstacles in the vehicle’s surroundings, whether during driving or during maneuvers at lower speeds. As in any radar system, the information about the presence of the target or obstacle is obtained by analyzing the reflected signal received as a consequence of the emitted electromagnetic signal. For detection, the decision to be made is whether the received signal corresponds to an obstacle, to an environmental interference (rain, wind, etc.) or simply to some electronic noise. We will apply statistical tests to compare the signal amplitude to a predetermined detection threshold or adapted from the actual data read. In our project, we will study the entire signal path. We will discuss from the generation of the electromagnetic wave and its format, through modulation and demodulation, to signal processing, which provides us with the desired information about the presence or absence of the target. Finally, modern systems do not operate with just one antenna, but with a sensor array, which is useful to reduce interference. Thus, we will also study space-time adaptive processing (STAP) techniques.
