DEVICE FORMING LOW-FREQUENCY DOPPLER SIGNALS Russian patent published in 1995 - IPC

FIELD: radiolocation. SUBSTANCE: device forming low-frequency Doppler signals has address decoder, address counter, spectrum width register, frequency register, sign flip-flop, amplitude register, two storages, clock pulse generator, three adders, six multipliers, two permanent storages, two code-to-voltage converters, two analog filters (of low frequency) with corresponding couplings to units of device. EFFECT: expanded application field thanks to enlargement of range of output frequencies, to setting and checking of negative values of velocities and to independent control over center frequency and spectrum width. 1 dwg
