Radar Transceivers: How To Connect The Antennas

There are different antenna options for transmitting and receiving a radar signal. This blog will focus on how to connect a monolithic microwave integrated circuit (MMIC) radar transceiver to the antennas in a way that guarantees an efficient transfer of the signals. mmWave MMIC to antenna interfaces At millimeter-wave (mmWave) frequencies, any transitions between two different transmission l... » read more

Radar For Automotive: How Far Can A Radar See?

In the previous entries of this blog dedicated to automotive radar, the reason for using radar and the principle of operation of the frequency modulated continuous wave radar were presented. Now, we will focus on the performance of the system, starting with its maximum detection range: how far can we detect an obstacle ahead? We need to have as much foresight as possible, to be able to detect a... » read more

Radar For Automotive: Basics Of FMCW Radar

Radar (acronym for Radio Detection and Ranging) uses radio waves to detect objects in the environment. It allows determining the distance (known as range), angular position (bearing), and velocity. Radar technology was developed for military use during World War II, but has now many civil applications, including air or marine traffic control, astronomy, ocean and meteorological monitoring, alti... » read more

Radar For Automotive: Why Do We Need Radar?

Communications and sensing technologies have transformed the automotive industry. More and more, cars include features and systems to interact with their environment, gaining awareness of the surrounding space, networking with each other and with the infrastructure, and detecting possible sources of danger. We can consider that vehicles have acquired their own “senses”: they know where they... » read more
