Simulator for Velocity Gate Pull-Off electronic countermeasure techniques

This paper explores the use of implementing deception waveforms in the space-time adaptive processing (STAP) model for efficient waveform optimization in hardware-in-the-loop simulation. By understanding range gate pull-off (RGPO) techniques developed in a generic form, velocity gate pull-off (VGPO) technique models can be explored in a similar manner. The VGPO mathematical models are developed using a STAP framework to simplify the optimization cost function. The STAP model, implemented in MATLAB, is solely used to represent a series of electronic countermeasure signals. Using the proposed implementation, the ECM waveform can be injected in the HILS architecture via simulation or hardware. Initial results reveal that the pulse-indexed STAP representation is M times better than a time-indexed signal representation while naturally including coordinated RGPO/VGPO.
