    • A semiconductor body (2) has a first region (5) of one conductivity type coupled to a first electrode (30). A second region (6) of the opposite conductivity type coupled to a second electrode (32) is provided within the first region (5) to form a first pn junction (7) with the first region (5). At least one further region (8) of the opposite conductivity type is formed within the first region (5) spaced from the second region (6) so as to form a further pn junction (10) with the first region (5) with each of the first and further pn junctions (7 and 10) making a contribution to the capacitance of the diode which capacitance varies in operation of the diode with a reverse-biasing voltage applied between the first and second electrodes (30 and 32). A coupling region (9) of the opposite conductivity type and more lowly doped than the second (6) and further (8) regions provides a resistive path for free charge carriers of the opposite conductivity type between the second (6) and further regions (8) and is sufficiently lowly doped that when a reverse-biasing voltage applied between the first and second electrodes (30 and 32) reaches a predetermined value during operation of the device, at least part of the coupling region (8) becomes depleted of free charge carriers to interrupt the resistive path and thereby resistively decouple the second (6) and further (8) regions so that the capacitive contributions of the first (7) and further (10) pn junctions are no longer coupled in parallel with one another by the resistive path and the overall capacitance of the diode is reduced.

    • A method of, and system for, communicating messages in an environment which is subject to fading, in which data to be transmitted is encoded and formatted, a checksum (CSM) is determined for said encoded and formatted data and in which the checksum (CSM) is added to an address code word (ADD) which is concatenated with the encoded and formatted message code words (M1, M2, M3) to form a message. A receiver is energized for receiving transmissions in its predetermined frame. In response to recognising its address code word the concatenated code words are decoded and stored. As each code word is stored, substantially simultaneously a checksum is computed for the message assembled so far and is compared to the checksum (CSM) in the address code word, if and when they are equal it is concluded that a complete message has been received and further analysis of the stored message is terminated.

    • In an FMCW radar system, the velocity of obstacles relative to the radar couples a Doppler frequency shift into the return signal which causes an error in the range measurement. It is known to use a radar signal having a frequency ramp that both increases and decreases to distinguish the range of an obstacle from its velocity but when multiple obstacles are present this is not practical. By using a measure of velocity from a succession of return signals, which of the radar output signals from the upsweep and downsweep of the radar signal that relate to a particular obstacle can be identified so that the range and velocity can be determined accurately. The FMCW radar system may be provided with a frequency scanned antenna, the beamwidth determined by the processing circuitry is variable according to the size of the obstacle being detected or the range at which the radar is searching for obstacles. Instead of scanning the beam of the radar, the variation in frequency can be made to alter the beamwidth of the radar so that, for example, a car radar will detect only vehicles in the lane ahead of the car, regardless of the range of the vehicles.
    • 在FMCW雷达系统中,相对于雷达的障碍物的速度将多普勒频移耦合到返回信号中,导致测距范围内的误差。 已知使用具有增加和减小的频率斜坡的雷达信号以区分障碍物的范围与其速度,但是当存在多个障碍物时,这是不实际的。 通过使用来自一系列返回信号的速度测量,可以识别来自与特定障碍物相关的雷达信号的上升和下降的雷达输出信号中的哪一个,使得可以准确地确定范围和速度。 FMCW雷达系统可以设置有频率扫描天线,由处理电路确定的波束宽度根据被检测的障碍物的大小或雷达正在搜索障碍物的范围而变化。 代替扫描雷达的波束,可以进行频率变化以改变雷达的波束宽度,使得例如汽车雷达将仅检测车前方的车辆,而不考虑雷达的范围 汽车。
