    • The invention relates to an antenna diversity comprising a first and a second antenna element one of which is operated in an active mode whereas the other one of which is operated in a parasitic mode. It is the object of the present invention to further minimize the amount of mismatch by still being able to maximize a predetermined signal quality criterion for the electromagnetic signal on the active path between the active antenna and the transceiver. This object is solved by a switching unit 120 for either operating the first antenna element in the parasitic mode and simultaneously operating the second antenna element in the active mode or vice versa and by providing a pre-selection unit 130 as well as a selection unit 140 for selecting an optimal configuration for the antenna diversity ensuring that the amount of said mismatch is below a predetermined threshold value and that simultaneously a predetermined quality criterion for the transceived electromagnetic signal is fulfilled best. The antenna diversity further comprises a control unit 150 for adjusting said selected configuration. The invention further relates to a method for operating such an antenna diversity.
    • 本发明涉及一种包括第一和第二天线元件的天线分集,其中一个天线元件以有源模式工作,而另一个以寄生模式工作。 本发明的目的是通过仍然能够使有源天线和收发器之间的有源路径上的电磁信号的预定信号质量标准最大化来进一步最小化失配量。 该目的由切换单元120解决,用于以寄生模式操作第一天线元件,并且以活动模式或反之亦然地操作第二天线元件,并且通过提供预选单元130以及选择单元140 用于选择用于天线分集的最佳配置,确保所述不匹配的量低于预定阈值,并且最好地满足用于收发的电磁信号的预定质量标准。 天线分集还包括用于调整所选择的配置的控制单元150。 本发明还涉及一种用于操作这种天线分集的方法。

    • In summary, a cancellation scheme for cancelling an effect of a direct feed- through from an output of a transmitter to an input of a receiver is proposed. The cancellation scheme comprises receiving a signal originating from the transmitter using a pseudo-noise code modulation based on a pseudo-random binary sequence signal in the receiver (S101), multiplying a signal generated based on the pseudo-random binary sequence signal by a programmable factor (S102) and subtracting a multiplication result from a signal generated based on the signal received by the receiver (S103). It enables a precise cancellation of the effect of the direct feed-through. Thus, digital noise occurring in the receiver due to the direct feed-through can be reduced. As a result, the maximum range of a radar system provided with the receiver can be increased and/or isolation requirements between transmit and receive antennas can be relaxed.
    • 总之,提出了一种用于消除从发射机的输出到接收机的输入的直接馈送的影响的取消方案。 取消方案包括:使用基于接收机中的伪随机二进制序列信号的伪噪声编码调制来接收来自发射机的信号(S101),将基于伪随机二进制序列信号生成的信号乘以可编程 因子(S102),并且从基于由接收器接收的信号生成的信号中减去相乘结果(S103)。 它能够精确地消除直接馈通的影响。 因此,可以减少由于直接馈通而在接收机中发生的数字噪声。 结果,可以增加设置有接收机的雷达系统的最大范围,并且可以放宽发射天线和接收天线之间的隔离要求。

    • The present invention relates to a RADAR transmitter for use in automotive vehicles, a method for generating a respective RADAR transmission signal and a modulation signal for control of an oscillating means for generation of the RADAR transmission signal. The RADAR signal, which may be generated according to the method of the invention by the transmitter by using a control signal for control of an oscillating means according to the invention, has a frequency spectrum with predetermined frequencies omitted such that it can easily comply with applicable regulations specified by the respective authorities. Therefore, the method, transmitter and modulation signal of the invention may also be used in any other RADAR applications where a frequency modulated RADAR signal is to be used and certain regulations with respect to the allowed use of transmission frequencies are to be met.

    • In a circuit (1) comprising first and second transmission lines (11,12) with first and second line widths, the transmission lines (11,12) are coupled to each other via a coupling (13,14) with first and second coupling widths at its ends, such that a smaller one of the line widths and a larger one of the coupling widths are combined, and such that a larger one of the line widths and a smaller one of the coupling widths are combined. Such a coupling (13,14) introduces relatively small reflection coefficients, for example for distances between ends of the transmission lines (11,12) smaller than a wavelength of frequency signals to be exchanged via the transmission lines (11,12) and the coupling (13,14). The circuit (1) can then become more compact. The coupling (13,14) may comprise one single taper or may comprise a first taper (13) with a first, larger coupling width and a second taper (14) with a second, smaller coupling width.
