Abstract: A method of using a directional sensor for the purposes of detecting the presence of a vehicle or an object within a zone of interest on a roadway or in a parking space. The method comprises the following steps: transmitting a microwave transmit pulse of less than 5 feet; radiating the transmitted pulse by a directional antenna system; receiving received pulses by an adjustable receive window; integrating or combining signals from multiple received pulses; amplifying and filtering the integrated receive signal; digitizing the combined signal; comparing the digitized signal to at least one preset or dynamically computed threshold values to determine the presence or absence of an object in the field of view of the sensor; and providing at least one pulse generator with rise and fall times of less than 3 ns each and capable of generating pulses less than 10 ns in duration.

Abstract: An apparatus for detecting the distance of an object from a signal transmitter during radiation of a transmitter signal uses a first capacitor which is initially short-circuited by means of a first switch and subsequently is charged from a constant current source following an opening of the switch. Upon a reception of an echo signal, the charge of the first capacitor is transferred to a second capacitor by closing a second switch at the time of the echo signal reception. The charge on the second capacitor, which is proportional to the elapsed time between transmitted and received signals, is delivered to an output via a low pass filter with the output signal representing a distance measuring signal.

Abstract: There is disclosed a range finder operating on the principle of finding the range of an object by measuring the time between transmission of a pulse towards an object and the reception of the reflected pulse. Errors in the range measurement caused by the different half-rise times of reflected pulses of different amplitudes are avoided by using only a reflected pulse of a predetermined constant magnitude as a measuring pulse for range determination. The desired magnitude of the measuring pulse is obtained by altering the power of the transmitter and/or by changing the amplification of the receiver. The use of pulsed laser range finders operating in the infra-red region of the spectrum is referred to for generating pulses as well as other sources of pulsed energy.
