Many radar sensors and communications systems need a multichannel filter-equalizer system that can be programmed by GUI for variable numbers of channels, each having independent center frequency, bandwidth, stop bands and equalization parameters. Military need includes systems to counter IEDs, multiband EA and EP radar systems and communication systems. Currently, programs resort to implementations consisting of parallel or switched banks of fixed bandwidth filters and passive equalizers. Digitally programmable multichannel filter-equalizers to perform filtering for varying signal environments is needed. Therefore, Systems & Processes Engineering Corporation (SPEC) will leverage our experience with our ADEP™ technology to create a ProgrammAble Multichannel Equalizing Filter System (PAMEF) designed so users can place multiple, independent bandwidth filters anywhere from 30 MHz to greater than 380 MHz. PAMEF will allow design of programmable filters having 0 dB gain over all channels while maintaining flatness of less than + 0.5 dB with -70 dBc in stop bands. PAMEF design permits all channels to have constant delay; it allows each channel to be independently equalized and signals from individual channels to be summed digitally or output separately to analog. Filter designs employ GUI based “draw your filter response” and low-level command programming syntax to minimize response time.
