Advanced Signal Processing Technologies for BMDS Radars

The objective is to formulate and validate via computer simulations new approaches for developing an algorithm suite having a capability for operating and processing wideband adaptive arrays and to counter interference. Selection of an efficient algorithm suite for both narrowband and wideband environments without a need for matrix inversion and independent of waveform type is the thrust. The goal is to achieve improvements in the signal-to-noise ratio (SNR) of the desired signal while suppressing the undesired signals. The approaches will be developed mathematically and will be validated via computer simulations. Algorithm simulation requires selection of physics based models for a phased array antenna, transmitted waveform, target, and jammer. Models from RDAS’ database will be used or where available models don’t suffice models will be generated. A three dimensional scenario wherein target and jammer locations are defined with respect to radar location will also be defined. Target, jammer and beam-steering motion will be incorporated in a simulation to demonstrate feasibility of the adaptive algorithm processing technique to continually suppress or cancel the jamming signal while preserving the information content of a reflected signal from a target regardless of motion. A planar array of size M×N will be used to demonstrate feasibility.
