Tradespace Performance Study of Polarization-Insensitive Spatial Filtering for Jamming Suppression

This paper presents a tradespace performance study of a recently published polarization-insensitive spatial-filtering algorithm used with a receive antenna array to suppress noise jamming. Since the new algorithm requires an intentionally incorrect description of the scenario's jamming environment, the algorithm has potentially numerous input settings which can be adjusted to produce various performance effects. After first identifying those input settings and the key performance metrics, this paper presents the results of a tradespace study of the algorithm's performance when various combinations of the inputs change. High-fidelity simulations of a practical jamming scenario demonstrate the algorithm's ability to trade among low total receive gains in the jammers' directions and high effective receive gain in a single desired emitter's direction.
