7.13.26. Time Delay Beamformer

The time delay beamformer reference design implements a time-delay beamformer that has many advantages over traditional phase-shifted beamformer. It uses a (full-band) Nyquist filter and Farrow-like structure for optimal performance and resource usages.

The design includes the following features so you can simulate and verify the transmit and receive beamforming operations:

  • Waveform (chirp) generation
  • Target emulation
  • Receiver noise emulation
  • Aperture tapering
  • Pulse compression
