pyArgus

This python package aims to implement signal processing algorithms applicable in antenna arrays. The implementation mainly focuses on the beamforming and direction finding algorithms. For array synthesis and radiation pattern optimization please check the "arraytool" python package. https://github.com/zinka/arraytool and https://zinka.wordpress.com/ by S. R. Zinka

Named after Argus the giant from the greek mitology who had hundreds of eyes.

Package organization:

• pyArgus: Main package
  • antennaArrayPattern: Implements the radiation pattern calculation of antenna arrays
  • beamform: Implements beamformer algorithms.
  • directionEstimation: Implements DOA estimation algorithms and method for estimating the spatial correlation matrix.

  • Fixed beamformers:
    • Maximum Signal to Interference Ratio beamformer
    • Maximum Signal to Interference Ratio beamformer with Godara's method
  • Adaptive beamformer:
    • Optimum Wiener beamformer (with known signal of interest direction)
    • MSINR with known covariance matrices
    • MMSE with known signal of interest

• Direction of Arrival Estimation:

  • DOA algorithms:

    • Bartlett (Fourier) method
    • Capon's method
    • Burg's Maximum Entropy Method (MEM)
