Abstract: |
Design proposed for reducing SINCGARS co-site interferers. Design uses 8 high-Q 5-zero notch filters with unique design techniques for very high Q. It uses 8 bandpass filters covering 1/8th the band for fast interferer acquisition. Once an interferer is recognized using log detectors and a microprocessor, the notch filter is tuned to the interferer for rejection. Unique techniques are also employed for the band-pass filters. The design approach will meet all of the system requirements. |
Benefits: |
This interferer reduction system will permit a SINCGARS radie to operate within the SINCGARS band and reduce the interferers to a low level with minimal affect on the radio performance. It will also provide new approaches to notch filters and band-pass filters which result in these filters having much higher Q's than previously achieved. |
