RADIO TRANSMITTER Russian patent published in 1998 - IPC

FIELD: telemetry systems for gathering information from mobile objects. SUBSTANCE: device has parameter check unit which is connected to interface unit, generator of modulation pulses which is connected to modulation input of amplitude modulator, which output is connected to input of power amplifier. In addition device has main and additional high-frequency oscillator, OR gate which first input is connected to output of interface unit and input of generator of control pulses; second input is connected to output of generator of control pulses and control input of commutator of high-frequency oscillations. Output of OR gate is connected to generator of modulation pulses. Second input of amplitude modulator is connected to output of multiplier, which input is connected to output of commutator of high-frequency oscillations, which commutation inputs are connected to main and additional high-frequency oscillators respectively. Output of power amplifier serves as device output. EFFECT: increased reliability of information receiving in conditions of reflected signals. 2 dwg
