Extremely suboptimal radar performance can occur if one or more of the following occurs: (High false alarm rates and/or low Pd) Heterogeneous Clutter Rapidly varying terrain Mountainous (rapid elevation/reflectivity variation) Rapid land cover variations (e.g., littoral) Dense Target Backgrounds Moving Clutter Military/civilian vehicles Large Discretes and Spiky Clutter Urban clutter Power lines, towers, steep mountainous terrain Range-Varying (Nonstationary) Clutter Loci Bi/Multistatics Nonlinear array geometries (e.g., circular arrays) One or More of the Above is Almost Always Present in Real-World Ops! 4

Tactic: Can the thermal engineer give the flight control engineer s briefing? Often cross fertilization can occur even if with only a 1 st or 2 nd order understanding of multiple disciplines Balance of depth and breadth How should engineering programs be structured in light of above? Undergraduate programs typically have the breadth, but don t seem to close the deal Example: Senior class semester devoted to dissecting a complex system Emergence of a Level 3 systems integration Multidisciplinary from its inception! 15
