Radar Transceivers: How To Connect The Antennas
By Marta Martinez Vazquez - 07 Sep, 2023 - Comments: 0

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
By Ed Sperling - 02 Aug, 2023 - Comments: 0

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?
By John Koon - 01 Jun, 2023 - Comments: 0

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
By John Koon - 10 May, 2023 - Comments: 0

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

High-quality ‘chirps’ for automotive, industrial mmWave radar Imec demonstrated a low-power phase-locked loop (PLL) that generates high-quality frequency-modulated continuous-wave (FMCW) signals for mmWave radar, which can be used in short-range automotive and industrial radar applications. The FMCW radars popular in healthcare, automotive, and industrial send out sinusoidal waves that get... » read more

Simulating Reality: The Importance Of Synthetic Data In AI/ML Systems For Radar Applications
By Arien Sligar - 09 Feb, 2023 - Comments: 0

Artificial intelligence and machine learning (AI/ML) are driving the development of next-generation radar perception. However, these AI/ML-based perception models require enough data to learn patterns and relationships to make accurate predictions on new, unseen data and scenarios. In the field of radar applications, the data used to train these models is often collected from real-world meas... » read more

Fixed-Point And Floating-Point FMCW Radar Signal Processing With Tensilica DSPs
By Cadence - 25 Jan, 2023 - Comments: 0

Automotive Advanced Driver Assistance Systems (ADAS) applications are increasingly demanding radar modules with better capability and performance. These applications require sophisticated radar processing algorithms and powerful Digital Signal Processors (DSPs) to run them. Because these embedded systems have limited power and cost budgets, the DSP’s Instruction Set Architecture (ISA) needs t... » read more

Physics-Based Radar Modeling: Driving Toward Increased Safety
By Ansys - 07 Dec, 2022 - Comments: 0

Autonomous driving is revolutionizing the global automotive industry. With every new model, cars are smarter and more capable of independently responding to external signals like lane markings, road signs, other cars and pedestrians. However, formulating a correct response via artificial intelligence depends on the flawless performance of the car’s perception systems, including radar-ba... » read more
