摘要： Threshold count pulses, the number of which being proportional to the slope of an impedance curve of a radiating antenna in an RF detection system, are counted in a first counter and, upon receipt of a read pulse representing a threshold of impedance, are transferred to a memory counter while the read pulse delayed resets the first counter. The values in these two counters are compared in a first comparator which emits a pulse if the value of the first counter is greater than that of the memory counter and in the absence of these pulses a sequencer emits a signal indicating a target is moving outwardly. The threshold count pulses also feed an AND gate together with pulses from the first comparator with the AND gate output being fed to a third counter. The third counter is compared in a second comparator which emits a pulse upon equality indicating the target has approached an inner boundary. The third counter is reset with delayed read pulses.
