Tactical Counter Concealment Aerial Sensors Electronic Protection (TC-CAS EP)

Tactical counter-concealment aerial sensors that are currently being developed by the U.S. Army operate at VHF, UHF and/or L-band frequencies. These radars must operate in environments in which there can be a significant amount of unintentional radio frequency interference (RFI) (i.e. communications, terrestrial broadcast, etc.), operating in close proximity to systems operating in similar radar bands and/or possibly hostile electronic attack (EA). The RFI and/or EA, which are received through an antenna"s mainlobe, sidelobes, and/or backlobes, can significantly degrade the image quality and adversely affect system capability. The primary objective of this Phase II SBIR is to develop a prototype consisting of detailed software simulation to demonstrate how well the proposed TC-CAS EP techniques would perform in complex EA and RFI environments. The techniques deemed feasible under the Phase I program will be refined and applied to available radar test data as provided by the U.S. Army or interested prime contractors to reduce future implementation risk as TSC works toward commercialization of the most promising EP techniques for current or future low frequency Army SAR/GMTI radars.
