    摘要： A high frequency carrier is provided which comprises: (a) a planar ceramic substrate having first and second faces and (b) at least one feed-through extending from the first face to the second face. The at least one feed-through comprises a pedestal of doped semiconductor that is at least partially surrounded by a conductive metal layer. Also described is an electrical assembly, which comprises the above high frequency carrier and a metallized substrate. The first face of the carrier is attached to the metallized substrate such that the at least one feed-through is electrically connected to the metallized substrate. The electrical assembly can also comprise at least one electronic element (such as an electronic component or an electronic circuit) that is attached to the second face of the carrier such that the at least one electronic element is electrically connected to at least one feed-through.

    摘要： A radar based sensor detection system comprises a microwave source operative to provide a continuous wave signal at an output. A pulse-former is coupled to the output of the source and is operative to provide at an output a variable length pulse that increases the transmitted energy of the radar system according to the range of object detection. A modulator is coupled to the output of the pulse-former for providing a modulated pulse signal when required. A transmit/receive switch coupled to the output of the modulator is selectively operative between a first transmit position and a second receive position. A transmit channel coupled to the transmit/receive switch transmits the pulse signal when the switch is operated in the transmit position. A receiving channel coupled to the transmit/receive switch receives the modulator signal when the switch is operated in the receive position. First and second voltage multipliers each have a local oscillator input for receiving the modulator signal in the receive position, and each have an input signal port, and an output port. A receiver channel receives a reflected transmitted signal from an object and applies the received signal to the receive signal input ports of the voltage multipliers. An autocorrelator coupled to the output ports of the voltage multipliers correlates the received signal to produce an output signal indicating the detection and position of the object.
