    摘要: 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.

    摘要: A time domain reflectometer (TDR) transducer (10) for determining a level (24) of liquid (16) in a container (12) includes a first electrode (34) and a second electrode portion (36) with a measuring volume (114) therebetween for receiving material (16) to be measured. The second electrode portion (36) has a shielded electrode section (36A) isolated from the first electrode (34) and an unshielded electrode section (36B), such that an energy pulse propagates along the shielded electrode section (36A) without signal loss, and boomerangs along a second opposite direction across the first conductive electrode portion (34), the measuring volume (114) and the unshielded electrode section (36B) where partial reflection of the pulse occurs at least at the interface (24) of the material (16) to create a return echo that travels in reverse direction, boomeranging back through the shielded electrode section (36A) for analysis by an electronic assembly (32).

    摘要: A system including a radar system (103). The radar system may include a transmit antenna, a receive antenna, and a controller. The controller may be configured to: determine or obtain information indicative of at least one of a phase of flight or an environmental condition; determine or obtain information indicative of a mission associated with the determined phase of flight and/or environmental condition; and based at least on the determined mission and the determined phase of flight and/or the environmental condition, tune radar parameters of the radar system to values to fulfill the determined mission associated with the determined phase of flight and/or environmental condition. The radar system may be reprogrammable by tuning the radar parameters to operate over any of a collection of phases of flight, any of a collection of environmental conditions, and any of a collection of missions.
