Acconeer, a specialist for pulsed coherent radar (PCR) and IoT is using the Rohde & Schwarz FSW85 signal and spectrum analyzer to develop a low-power pulsed coherent radar sensor that operates in the 60 GHz unlicensed frequency band and is particularly suited to IoT applications.
The Acconeer A111 is a PCR low-power radar sensor for battery powered IoT devices. It can be used for many applications such as gesture control, material recognition, object and presence detection as well as level and speed measurements.
An excellent signal-to-noise ratio (SNR) and high bandwidth are crucial for these applications. To maximize the SNR, Acconeer's design engineers need to ensure that the shape of the radar pulse is optimized without violating the spectrum regulations for short range devices. The engineers use the state-of-the-art R&S FSW analyzer with the R&S FSW-B8 resolution bandwidth option to visualize the frequency spectrum.
Josefin Strahl, Head of Hardware Integration at Acconeer stated that the analyzer features very good SNR in the V band frequency range of the radar (57 GHz to 64 GHz), due to resolution bandwidth option. He also adds that the Acconeer has substantial experience of using Rohde & Schwarz equipment, and are satisfied with the company's top-level T&M solutions.
The R&S FSW is used in the verification process to visualize the radar pulse in both the time and frequency domain because it is one of the few instruments on the market that can visualize the radar pulse frequency spectrum. Users can measure the spectral density, band power, root mean square (RMS) power and peak power. The R&S FSW can even perform challenging measurements such as 99% occupied bandwidth thanks to its excellent SNR.
To address the growing trends in IoT applications and devices, Acconeer has started specializing in small radar solutions for consumer products.
