[ Instrument R&D of Instrument Network ] Millimeter wave radar is a radar working in millimeter wave (millimeter wave) detection. Usually millimeter wave refers to the frequency range of 30~300GHz (wavelength is 1~10mm). The wavelength of millimeter waves is between centimeter waves and light waves, so millimeter waves have the advantages of microwave guidance and photoelectric guidance.
It is reported that Rohde & Schwarz provides R&S FSW85 signal and spectrum analyzers for pulse coherent radar (PCR) and Acconeer in the field of Internet of Things. Acconeer will use R&S FSW85 to develop the A111, a low-power pulsed coherent radar sensor that can operate on the 60 GHz unlicensed frequency band and is particularly suitable for Internet of Things (IoT) applications.
A spectrum analyzer is an instrument that studies the spectrum structure of electrical signals. It is used to measure signal parameters such as signal distortion, modulation, spectral purity, frequency stability, and intermodulation distortion. It can be used to measure certain circuit systems such as amplifiers and filters. Parameter is a multi-purpose electronic measuring instrument. It can also be called frequency domain oscilloscope, tracking oscilloscope, analysis oscilloscope, harmonic analyzer, frequency characteristic analyzer or Fourier analyzer, etc.
Modern spectrum analyzers can display the analysis results in an analog or digital manner, and can analyze electrical signals in all radio frequency bands from very low frequencies below 1 Hz to sub-millimeter wave bands. If the digital circuit and microprocessor are used inside the instrument, it has storage and calculation functions; with a standard interface, it is easy to form an automatic test system.
The number of IoT applications and devices is increasing, and the application of sensor technology in consumer devices is also becoming more common. In response to these growing demands, Acconeer, headquartered in Lund, Sweden, specializes in providing small radar solutions for consumer products.
Due to its small footprint, the Acconeer A111 PCR low-power radar sensor is particularly suitable for battery-powered IoT devices. A111 can be used for a variety of applications, such as gesture control, material recognition, object and presence detection, and level and speed measurement. Excellent signal-to-noise ratio (SNR) and high bandwidth are critical for these applications.
In order to improve the signal-to-noise ratio, Acconeer's design engineers need to ensure that the shape of the radar pulse is optimized without violating the short-range device spectrum plan. These engineers use the R&S FSW-B8 resolution bandwidth option R&S FSW analyzer to observe the spectrum. During the verification process, R&S FSW can observe radar pulses in the time and frequency domains, because it is one of the few instruments on the market that can observe the radar pulse spectrum.
In addition, users can measure spectral density, band power, root mean square (RMS) power, and peak power. Thanks to its excellent signal-to-noise ratio, R&S FSW can perform challenging measurement tasks, such as 99% occupied bandwidth testing.
Josefin Strahl, head of hardware integration at Acconeer, said: "As a growing company focused on technological innovation, we are pleased to be able to use R&S FSW to push the test limits. With the resolution bandwidth option, the R&S FSW analyzer is in the radar V-band frequency range ( 57 GHz to 64 GHz) has an excellent signal-to-noise ratio, which is particularly useful for our products.
Johan Nilsson, Product Manager, Spectrum and Signal Analyzer, Rohde & Schwarz, said: "We are very pleased to provide a powerful R&S FSW signal and spectrum analyzer for a dynamic and growing company like Acconeer. These companies focus on including Innovations in the field of technology trends including networking are assisted by them.
About the sensor
The sensor is a detection device that can sense the measured information, and can convert the sensed information into electrical signals or other required forms of information output according to a certain rule to meet the transmission, processing, storage, and display of information , Recording and control requirements. Better sensor technology gives people a smarter world.
