SiCOM proposes to develop a low-complexity, high-performance ESM digital receiver module based on SiCOM's revolutionary Self-Similar Optimal Detection (SODET) technique. SODET offers a solution to a classic problem in conventional ESM receivers: optimal signal detection requires a detection bandwidth matched to the signal, so any system which must process many signal types with many different parameters must use an impracticably large number of processing bandwidths. The conventional solution is to use a small number of bandwidths (usually one) to keep within physical and cost constraints, resulting in excessive sensitivity loss for most signals. SODET dynamically optimizes the detection bandwidth for any signal, detecting every signal with negligible degradation from optimal sensitivity, regardless of its signal bandwidth. In Phase I SiCOM will design a digital receiver module that balances the conflicting requirements of high spurious-free dynamic range, ADC performance, wide bandwidth, power, size, and cost. SiCOM will also develop a simulation model to predict, simulate, and demonstrate the performance against a postulated set of battlespace signals. In Phase II, SiCOM will develop and test a field-programmable gate-array (FPGA)-based breadboard SODET-based digital receiver module, and in Phase III SiCOM will develop a digital receiver using an ASIC-based SODET Processor.
