Overview

The application macro computes and displays an inverse synthetic aperture radar (ISAR) image from the backscattered radar cross-section (RCS) data over frequency and angle.

Windowing functions, resampling and extracting the local maxima positions to file are supported. The application macro requires a far field RCS request or far field RCS data imported from a file containing far field data (.ffe file). Data imported from a .ffe file must be added manually to a 3D view.

The application macro comes in two primary parts:
  1. PF_ISAR.lua: The main POSTFEKO application macro to calculate and display ISAR results.
  2. CF_ISAR_Resolution.lua: A CADFEKO application macro that helps to set up the frequency and angular sampling for the required ISAR image resolution and range.
