Abstract
An adaptive, fail-soft digital filterbank for digitized Doppler-modulated video signals. A plurality of modules are controlled by the impulse filter weighting technique to each respond to a set of discrete Doppler frequencies. A built-in test feature is included, the module inputs being multiplexed between system digitized video and synthetic signals to continuously confirm proper operation. Module failures are recognized by the control (programming) circuitry and spare modules can be activated. Control and communications link circuitry is constructed with multiple redundancy.
