Our Products

Radome Measurement System

We are proud to present our new product, the Radome Measurement System (RMS) for the automotive radar frequency band from 76 to 81 GHz. The RMS enables radar cover (radome) analysis and material characterization combined in one device. The system can be used in laboratory for development/quality control and in production for end-of-line testing.

Radar Target Simulator

perisens offers high quality radar target simulators for the automotive radar bands 24G and 77/79G. Our systems allow the simulation of range, relative target speed and radar cross section and cover the full bands with an instantaneous bandwidth of 200MHz (24G) and 5,000MHz (77/79G). The systems are used as reference targets in sensor production and as test systems for Research and Development.

Frequency Converter

perisens provides high quality frequency converters covering the automotive radar bands 24G and 76/77G. Our combined Up- and Downconverters allow fully calibrated signal analysis and signal generation at millimeter wavelengths using cost effect measurement devices at low GHz frequencies.

We are looking forward to a good cooperation on the same wavelength.

Merry Christmas and a Happy New Year

We thank our customers and partners for the confidence and the collaboration on the same wavelength.

For 2021 we wish you nothing but the best and many innovative ideas in all frequency ranges. Have a peaceful, relaxing holiday season and a prosperous New Year!

Our this year’s christmas card was measured with our product the Radome Measurement System (RMS-77/79G) equipped with a scanning positioning unit.
It shows a spatially resolved transmission image of a christmas tree sprayed onto a PET foil in amplitude and phase. The tree is sprayed in uni green and the balls in metallic silber.  The 100um thick uni paint gives an additional phase shift of ~6 degree with minimal impact on the attenuation. The metallic paint of only 20um gives a phase shift of 10 degrees and increases the 1way attenuation by 0.7dB. Due to the increasing demands of highly automated driving functions, it is important to investigate the influence of painted surfaces (e.g. bumpers) on automotive radar sensors. The RMS enables materials characterization of automotive paint and measurement of painted radar covers (as bumpers).

Here you find more information about the RMS.

Specification of the christmas card:

  • Frequency 76.5GHz
  • Transmission image with 51 x 84 pixel of each 3mm size
  • PET foil with Dk=3.22 and d=350um
  • Uni gree paint with Dk=2.3 and d=100um
  • Metallic silber paint with Dk=31 and d=20um

All electrical properties measured with RMS-77/79G, perisens.

Radar Workshop
Our CEO Dr. Florian Pfeiffer gives you insights about automotive radar technology covering the following topics:

  • Radar as key technology for automotive sensing
  • Basics in radar technology (electromagnetic wave properties and propagation effects)
  • Measurement principles for distance, velocity (Doppler) and direction of arrival (DoA)
  • Automotive sensor performance (24/77/79GHz radar vs. other sensor technologies)
  • Radar signal processing (from raw data to high-level object data)
  • Future trends in automotive radar
  • Design priciples of radar covers (radome) and influrence on the radar performance
  • Relevant material properties (plastic and paint) of radar covers
  • Radar calibration and radome measurement techniques

Contact us for further information.

New Office
We moved to a new office in Feldkirchen b. München (10min from Munich Trade Fair). Our team is growing and the space at our old location was tight. With 400 square meters, the new premises offer us plenty of space for laboratory and office use.

Thanks for everyone’s support through the years!

Here you find our new adress and telephone number.
