Radar vs. PIR: Selecting the Right Solution


As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar's enhanced features, it's essential to reassess whether PIR remains the best choice for your specific application or if radar's advantages can bring greater value. The purpose of this material is to provide a... » read more

Radar-Based Vital Signs Detection For In-Cabin Applications


Radars have been at the forefront of the automotive industry for some time now. They play an integral part in advanced driver assistance systems (ADAS) and aid in applications such as adaptive cruise control, collision mitigation, blind spot detection, lane change assist, and many other applications. In-cabin sensing is an emerging area in the automotive industry, and radars play an integral... » read more

Sensor Requirements For Developing Robust Environment Perception Systems


In recent years, sensor systems for environment perception have become increasingly important – whether for adaptive robotics, automated driving, industrial process and quality control, or condition monitoring. The aim is always to detect and interpret certain environmental characteristics. In doing so, it’s important to choose not only the right algorithm but also the right sensor or senso... » read more

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

New Approaches To Sensors And Sensing


Sensors are becoming more intelligent, more complex, and much more useful. They are being integrated with other sensors in sensor fusion, so a smart doorbell may only wake up when it’s imperative to see who’s at the door, and a microphone may only send alerts when there are cries for help or sounds of glass breaking. Kim Lee, senior director of system applications engineering at Infineon, t... » read more

How Many Sensors For Autonomous Driving?


With the cost of sensors ranging from $15 to $1,000, carmakers are beginning to question how many sensors are needed for vehicles to be fully autonomous at least part of the time. Those sensors are used to collect data about the surrounding environment, and they include image, lidar, radar, ultrasonic, and thermal sensors. One type of sensor is not sufficient, because each has its limitation... » read more

Designing Crash-Proof Autonomous Vehicles


Autonomous vehicles keep crashing into things, even though ADAS technology promises to make driving safer because machines can think and react faster than human drivers. Humans rely on seeing and hearing to assess driving conditions. When drivers detect objects in front of the vehicle, the automatic reaction is to slam on the brakes or swerve to avoid them. Quite often drivers cannot react q... » read more
