Automotive Digital Radar Reference Design


Altera’s automotive digital radar reference design lets you easily develop and verify hardware accelerators using our advanced development tools. It demonstrates how an FPGA can be used as a hardware accelerator for basic continuous wave frequency modulation (CWFM) type automotive radars. Its hardware and software design methodology enables you to develop digital radar processing floating-point fast Fourier transform (FFT) accelerators, digital beamforming, and fixed-point finite impulse response (FIR) filtering without hand coding register transfer level (RTL). Use this design as a starting point for radar designs to which you can add additional processing algorithms.


The main features of this reference design are:

  • Develop a floating-point FFT hardware accelerator, digital beamformer, and fixed-point FIR filter using our DSP Builder Advanced blockset within MATLAB Simulink. Allows for automatic generation of register transfer level (RTL) from the DSP Builder model.
  • Hardware verification of the DSP Builder model using system in the loop via a MATLAB application program interface (API) developed by Altera. Provides ability to verify the design at system clock speed on actual hardware instead of needing to simulate RTL.
  • Integrates the hardware accelerator into an embedded system using Qsys system design tool and Nios® processor II as the host.

Demonstrated Altera Technology:

  • Cyclone® V GX FPGA
  • Nios II processor
  • DSP Builder Advanced blockset
