Abstract
Land Forces D-Sigs-EM has initiated a task called SCAR (Signal Classification And Recognition) for the development of an intercept/analysis test-bed by CEW (Communications EW Section). Using state-of-the-art technology to process a huge amount of data with sophisticated algorithms, the system will, hopefully, be able to assist and to increase the efficiency of an operator in monitoring the High Frequency (HF) and Very High Frequency (VHF) bands. The ACES test-bed, in its preliminary stage, will consist of a wideband digital receiver, an energy detection subsystem (Fast Fourier Tranform (FFT) processors and wideband Digital Signal Processors (DSPs)), digital drop receivers (DDR), and a narrowband DSP subsystem. At a further stage, more receivers will be incorporated as well as a sophisticated DFACTT (Data Fusion and Correlation Techniques Test-bed) subsystem developed by CEW, which has already successfully passed through field trials with the Land Forces. This subsystem will provide to the ACES test-bed, very high level man-machine-interface abilities, increasing significantly the operator's efficiency in interpreting intelligence information. As part of the narrowband subsystem, Automatic Modulation Recognition (AMR) algorithms are currently being investigated. TRUNCATED
