Radar Systems

It started with a simple FMCW radar for counting birds in the sky up to a height of 1 km. We have since evolved and offer customized radar solutions based on our modular software-defined Radio (SDR) hardware with a highly versatile radar processing realtime DSP engine.

We took our SDR and coined the name of our radar platform Software Defined Radar.

We have sucessfully developed several radar frontends for our embedded SDR platform. Currently, we can offer a selection of wideband IQ daughterboards (1x1 wideband), highly integrated FMCW- and LO-mixers modules, High-stability and low-noise local oscillators.

• FMCW and Arbitrary Waveform Radars
  • TX frequency range: 8200-9600 MHz and 9200-10600 MHz
  • TX Output power: 33 dBm
  • TX waveforms loadable from linux user space
  • Chirp bandwidths up to 160 MHz
  • RX baseband streaming interface implemented with open-source API "libiio"
  • RX direction of arrival estimation
  • FPGA coprocessors for range-doppler post-processing
  • Real-time adaptation of radar parameters such as PRF, chirp interleave mode, carrier etc.
  • Multi-device synchronization with GPS

Examples of some of our specialized 8.2-9.6 GHz SDR frontend boards that are used for a drone radar.

Based on our embedded SDR platform, miniCODIR is a standalone software defined radar. It is designed to provide maximum versatility for your cognitive radar implementations. FPGA-based DSP algorithms enable future implementations for varying use-cases.

Radar data post-processing may be performed by a co-processor on the SDR itself, with enough power for most customer-specific applications. Alternatively, data streaming to a post-processor is supported out-of-the-box.

We selected a well-established and open-source driven API called “libIIO” for data streaming and radar parameter configuration. libIIO is widely used and supported out-of-the-box by the most popular signal processing software.

miniCODIR supports two operational modes: “FMCW” and “arbitrary TRx”.

FMCW Mode

A signal generator in the FPGA generates chirp signals with real-time adaptable radar parameters such as pulse repetition frequency, chirp-interleave mode, chirp bandwidths, and sweep times. The received echo signal is mixed down by direct conversion with a time-delayed reference chirp.

Arbitrary TRX Mode

A signal generator in the FPGA is capable of generating arbitrary signals such as noise signals or non-linear modulated chirp signals with up to 80 MHz bandwidth. TX waveforms are loadable from the Linux user space. Received echo signals are processed with a double-heterodyne receiver optimized for maximum dynamic range and excellent receiver noise figure.
