Modern automotive embedded systems with special mention to radars

Electronics and embedded systems have become an increasingly integral part of modern automobiles. Automotive embedded systems are a class of embedded systems which are based on the concept of generic embedded systems but vary widely in terms of design constrains, operating environments, performance goals and many other factors. This paper serves as a review of the recent trends of automotive embedded systems with a special mention to radars. The paper opens with an overview of automotive embedded systems, their design and their development methods. Then it discusses in-vehicle networks and the CAN bus. Subsequently, it discusses automotive radars and their design. The principles and mathematical concepts behindautomotive radar signal processing have been described in detail. Then the applications of such radars are discussed briefly followed by the design constraints. The paper concludes with a remark on the future scope of automotive radar systems.
