Изобретение относится к радиолокационной технике, а более конкретно, к радиолокационным приборам индивидуального пользования, например, для экипировки пожарных и спасательных групп, спелеологов, а также для реабилитации слепых людей. Задача, на решение которой направлено изобретение, состоит в обеспечении эффективного подавления паразитного сигнала, обусловленного ограниченностью полосы пропускания, и изменении коэффициента стоячей волны тракта и мощности задающего СВЧ-генератора при перестройке его частоты. Для достижения указанного технического результата в известный частотно-модулированный радиолокатор, работающий в СВЧ-диапазоне длин электромагнитных волн, дополнительно введена схема компенсации паразитного сигнала, состоящая из блока формирования компенсирующего сигнала и блока вычитания. Предпочтительно, чтобы блок формирования компенсирующего сигнала содержал последовательно соединенные первое ключевое устройство, блок памяти и второе ключевое устройство, а также переключатель работа - калибровка. Возможность эффективного подавления паразитного сигнала обусловлена тем фактом, что и полоса пропускания, и коэффициент стоячей волны СВЧ-тракта, и изменение мощности СВЧ-генератора в полосе перестройки являются практически неизменными во времени.The invention relates to radar technology, and more specifically, to individual use radar devices, for example, for equipping fire and rescue teams, cavers, as well as for the rehabilitation of blind people. The problem to which the invention is directed, is to provide effective suppression of the spurious signal due to the limited bandwidth, and changing the coefficient of the standing wave of the path and the power of the master microwave generator when tuning its frequency. To achieve the specified technical result, a well-known frequency-modulated radar operating in the microwave range of electromagnetic wavelengths has additionally introduced a parasitic signal compensation circuit consisting of a compensating signal generating unit and a subtraction unit. Preferably, the compensating signal generating unit comprises a first key device, a memory unit and a second key device, as well as an operation-calibration switch, connected in series. The ability to effectively suppress the spurious signal is due to the fact that the passband, the coefficient of the standing wave of the microwave path, and the change in the power of the microwave generator in the tuning band are practically unchanged in time.
