DOD electronic warfare cry for help

Under-fund something enough for years while patting yourself on the back that you are the best, and eventually you get this:

Based on U.S. and foreign radar weapon system developments, the USAF EW community has become increasingly concerned about the current state of practice of EW receiver's ability to address radar waveform agility advancements and the complex electromagnetic operating environment that are part of the modern battlefield. These modern agile threats include adaptive/interleaved multi-mode waveforms based on engagement scenarios; use of Active Electronically Scanning Array (AESA) antennas; wide RF operating bandwidths and agilities; variable pulse widths (including very long) with coded modulations; and including operations within multi-signal and dense background RF environments. EW receiver functions include Radar Warning Receivers (RWR), EW jamming system Receiver/Processors (R/P), Intelligence Surveillance and Reconnaissance (ISR), Electronic Support Measures (ESM), and other applicable RF receivers


In 2012 AFLCMC/XZ directed a series of studies to assess AESA radar capabilities and their impacts on legacy EW systems. In 2013, in conjunction with AFRL/RYW, a study was conducted specifically to identify characteristics of modern/future agile radar threat waveforms; assess key threat waveform drivers on EW receiver types, and to propose candidate EW receiver architecture and concepts of operation. The results of these study efforts are provided as classified attachments and help to define the RFI focus.
