Demonstration of Advanced Detection Techniques Against Low Probability of Intercept Avionics Waveforms

The proposed Advanced LPI Processor (ALPIP) will enable a single-site, stand-alone ELINT system to be built that detects, DFs and identifies cruise missiles. The system will feed hostile emitter line-of-bearing and SEI data to a multi-sensor tracker forthe production of a fused air picture and for air vehicle engagement by hard-kill weapons. The ALPIP will detect the majority of fielded cruise missiles using multiple antennas and advanced processing algorithms tailored to the cruise missile problem.The Phase I design will incorporate modified COTS receiver hardware and will be tailored to fit into an existing ELINT/ESM suite, to simplify Phase II work and to reduce the time to IOC.The algorithms developed for this receiver will be applicable to ESMsystems in F-22 variants, the JSF, Aerial Common Sensor and perhaps DD 21 and CVN 77. The US Army ALPIP-enabled cruise missile detection system will be useful to deployed and CONUS Army, Navy and Air Force units, in addition to coalition/allied forces incombat theaters worldwide.
