Radar converter raises in-cabin monitoring with 60GHz parameter

Tue, Sep 13, 2022

At European Microwave Week later this month, dSpace will unveil its DARTS HBC-7066V radar converter for validating in-cabin monitoring systems.

Automated driving from SAE level 3 upwards mandates that the driver and passengers must be permanently monitored to ensure that the driver can take the steering wheel at any time and that passengers remain in their seats. For monitoring the interior space, radar systems operating at 60GHz are the first choice, said dSpace.

The company has extended its range of radar target simulation with the DARTS HBC-7066V in order to test the radar sensors used for such tasks. The introduction of the converter makes it possible to operate any dSPace Automotive Radar Test System (DARTS) in the 60GHz V band. This also applies to DARTS in the field.

The convenient over the air (OTA) test method of the DARTS product family enables engineers to validate the entire sensor transmission channel. The small size of the converters makes them suitable for in-vehicle use, added the company.

Used in combination with various other DARTS devices, special test requirements such as distances of less than one meter, or processing bandwidths of up to 5GHz, are supported.

dSpace Automotive Radar Test Systems (DARTS) are suitable for a wide range of applications in the development process of radar sensors and vehicles equipped with these sensors. Typical applications can be found in chip design, controller testing, vehicle testing, end of line testing and vehicle homologation.

Visitors to the dSpace stand (B28) at European Microwave Week, in Milan, Italy, 25 to 30 September, will be able to see the 60GHz radar converter in a product demo.

dSpace provides simulation and validation products for developing connected, autonomous and electrically powered vehicles. The company’s range is used by automotive manufacturers and their suppliers to test the software and hardware components in new vehicles long before a new model is allowed on the road.

Engineers also rely on dSpace for aerospace and industrial automation. Its portfolio ranges from end-to-end solutions for simulation and validation to engineering and consulting services as well as training and support.

The company is headquartered in Paderborn, Germany, and has three project centres in Germany, and serves customers through regional dSpace companies in the USA, the UK, France, Japan, China, Croatia, and South Korea.

Two models extend R&S signal and spectrum analyser frequency range

Mon, Sep 12, 2022

Two models have been added to the Rohde & Schwarz signal and spectrum analyser family, taking the available frequency range up to 50GHz.

The R&S FSV3050 and R&S FSVA3050 have been added to the FSV family of high speed analysers with up to 200MHz analysis bandwidth for lab and production 5G NR testing.

The FSVA has a high dynamic range and phase noise of -127dBc/Hz (f_centre is 1.0GHz, 10kHz offset). It has up to 1.0GHz analysis bandwidth to perform demanding measurements such as linearising power amplifiers, capturing short events and characterising frequency agile signals.

The main driver for 50GHz models is 5G NR applications. The FR2 band n262 spans 47.2 to 48.2GHz, covered by these 50GHz models in default configuration. The R&S FSV3-B54G option for the FSVA enables signal analysis up to 54GHz, which also includes the upper edge of the FR2-1 band at 52.6GHz. This is suitable for the aerospace and defence industry in which 47.2 to 50.2GHz and 50.4 to 51.4GHz are filed at the ITU (International Telecommunication Union) for geostationary satellite systems. Applications include the production of components like filters, amplifiers or travelling wave tubes.

The FSV3-B710 enhanced performance option is available for the 50GHz variants. It is available for the two new FSV and FSVA variants, enhancing phase noise performance, lowering DANL (displayed average noise level) and, for FSVA, provides low-end frequency range extended to 2.0Hz.

The R&S FSV3-B54G und R&S FSV3-B710 options for R&S FSV and R&S FSVA family are now available from Rohde & Schwarz. They will be exhibited at European Microwave Week (EuMW) at stand D18. The exhibition runs from 27 to 29 September, 2022 at the Milano Convention Centre, Italy.

Rohde & Schwarz was founded more than 85 years ago. It specialises in test and measurement, technology systems and networks and cybersecurity. company is headquartered in Munich, Germany.

Image sensor is adaptive for all vehicle occupants

Fri, Sep 09, 2022

In-car safety and comfort in automotives is advanced with the VD/VB1940 DMS (driver monitoring system) sensor, a hybrid sensor for interior monitoring, announced by STMicroelectronics.

Leading automotive markets start to mandate driver monitoring systems (DMS) reported STMicroelectronics. While DMS promises greater road safety by assessing driver alertness, ST said that its next-generation dual image sensor monitors the full vehicle interior, i.e., the driver and all passengers. The sensor enables new applications such as passenger safety-belt checks, vital-sign monitoring, child-left detection, gesture recognition and high-quality video/picture recording.

The image sensor uses ST’s second-generation 3D-stacked back-side illuminated (BSI) wafer technology, which maximises the optical area and on-chip processing in relation to die size. This lets the sensor perform sophisticated algorithms locally for optimal performance in both colour and near-infra-red (NIR) imaging, saving power and relieving demand for an external co-processor.

Algorithms performed on-chip include Bayer conversion and HDR merging for optimal image-quality and frame rate. On-chip Bayerisation processing enables the user to reshuffle the colour pixels of the RGB NIR 4X4 pattern into RGGB format compatible with a range of SoCs. Local processing also handles independent colour and NIR pixel-exposure optimisation for optimum image quality in both modes, as well as smart upscaling to maximise NIR image resolution by capturing extra NIR information from RGB pixels.

The VD/VB1940 sensor combines the sensitivity and high resolution of infra red sensing with high dynamic range (HDR) colour imaging in a single component. It can capture frames alternatively in rolling-shutter and global-shutter modes. With 5.1Mpixels, it captures the high dynamic range (HDR) colour images needed for an occupant monitoring system (OMS) in addition to the high-quality NIR images typically captured by standard DMS sensors. DMS uses NIR imaging to analyse driver head and eye movements in all lighting conditions.

Offered in both bare wafers (VDB1940) and packaged in BGAs (VB1940), samples are available now and mass production is planned to meet model-year 2024 vehicles being designed now.

Qualified to AEC-Q100, the VD/VB1940 is ISO 26262 compliant to facilitate use in functional-safety systems up to ASIL-B.
