Abstract: This two-part papcr prcscnts a coinpreheiisive approach to practical space-time
adaplivc processing (S'L'AP) for airbrrrnc phased array applications. Part I reformulates the JDL
algorithm to removc rcstrictioiis placcd by the original developmenr for idcal linear arrays of point
sensors. In doing so the pcrtimnaticc ol'llic JDL algorithm is sigtiificnntlyimproved in simulations
nnd in mcasured data. Thc paper deals with STAP in hornogencous and non-lirmiugcnenus
cnviroinnciifs with Part 1 rocusing on homogctieoiis cnvimmcntx arid Part 2 tloaling with STAP
