Phased Array System Toolbox

Temporal Signal Processing

After a signal has been propagated through the receiver array and receiver front end, you can process the resultant radar cube using a number of temporal signal processing techniques provided by Phased Array System Toolbox, including:

  • Time-varying gain control (TVG)
  • Pulse compression
  • Matched filter with spectrum weighting option
  • Coherent and noncoherent integration
  • Stretch processing
  • Dechirp

At this point in the processing chain, the system toolbox provides algorithms for the detection and estimation of parameters of interest, such as range and Doppler. The following signal processing tools enable you to numerically characterize and visualize the detection performance of your system:

  • Constant false alarm rate (CFAR) processing including cell-averaging (CA), greatest-of cell-averaging (GOCA), smallest-of cell-averaging (SOCA), and order statistic (OS)
  • ROC curve visualization
  • Neyman-Pearson detector threshold
  • Albersheim and Shnidman equations
