SBIR-STTR Award

S.T. Research proposes to develop optimgic, algorithms, and processing speeds for airborne use of IFM receivers in the LT mode of operation. The effect of LT on IFM pulse processing is not well documented, and a thorough analysis of these effects, and solution of the problems caused by the LT process is the goal of this SBIR effort. S.T. Research Corp. has developed and fielded High Probability of Intercept (HPI) IFM based receiver systems which are installed and deployed on the Los Angeles class of submarines. The HPI system is capable of quickly detecting and identifying large numbers of emitters in dense signal environments in order to meet exacting submarine operational requirements. The STR HPI receiver wi used to analyze the operation of an IFM based receiver in the LT mode. Test emitters will be generated in the STR Electronic warfare (EW) laboratory, and algorithm development and analysis will be performed on the HPI receiver system. Algorithms will be developed for analyzing and identifying emitters in the presence of interfering signals. System performance will be analyzed to determine the probability of intercepting radar emitters. Feasibility of implementing an IFM receiver in the airborne environment will be determined.
