Abstract In order to understand the principles of space-time adaptive processing, several interactive MATLAB demonstrations are presented. These demonstrations allow the user to explore the effects of various parameters on radar performance. An airborne radar scenario is presented with user control over flight parameters (ground velocity and ground heading) and radar parameters (pulse repetition frequency, antenna orientation). The azimuth-Doppler relationship of clutter is updated continuously to illustrate the effects of each parameter. The user also has the option to show the adapted pattern of the full space-time adaptive weight vector with the chosen parameters. Another option allows the user to explore the spatial array patterns in the presence of various interference scenarios, including discrete and continuous jammers, wideband interference, and clutter within a single Doppler cell. This demonstration also explores the effects of various array configurations. Many of the movies and data presentations shown at other ASAP workshops are available for closer scrutiny. Additional movies that show Mountaintop terrain-scattered jamming and Mountaintop IDPCA data are available for display.
