    摘要: A continuous signal of a radio frequency source is connected to an antenna using at least one mixer to generate and analyze radar pulses. To generate a radar pulse, the at least one mixer is briefly placed into a state of low throughput loss. After the radar pulse is generated and transmitted, the at least one mixer is switched over to a receive mode to analyze a mixed signal formed by a receive signal, in particular at least one radar pulse reflected by an object, and the continuous signal of the radio frequency source.

    摘要: Mixer unit for a radar sensor for motor vehicles, having an I mixer and a Q mixer which are connected in parallel branches between an oscillator port and an RF port with the aid of power splitters. A switch is situated between each of the power splitters and the Q mixer which allows the signal arriving from the power splitter to be selectively decoupled from the Q mixer and switched to a high-frequency ground. A transformation element is provided between the high-frequency ground and the particular node point of the power splitter which transforms the high-frequency ground into an open line at the node point.

    摘要: In a radar sensor, a continuous microwave signal is passed through an RF switch which is periodically controlled by a pulse signal. The pulse signal is frequency modulated in such a way that the spectrum of the pulse signal is expanded without decorrelation occurring. Using this arrangement, the noise level is kept low and the detection range is increased.

    摘要: It is therefore the object of the present invention to disclose a device for power calibration of an oscillator in the high-frequency range, which has a reduced number of components and/or has less-expensive components. A method for power calibration of an oscillator is also to be disclosed, which eliminates the disadvantages of the known methods, that is, determining the output power of the oscillator via an additional, expensive component. To that end, the input (31) of the control module (40) is embodied as electrically connectable to the HF switch (comprising (22) and (24)) and the output (34) of the control module (40) is embodied as electrically connectable to the HF switch and/or to the amplifier. If the HF switch is then not acted upon by an input signal (pulse or direct voltage), but instead if the voltage is measured at the control input (30) of the HF switch, then the required controlled variable (the HF output power) is achieved, since the PIN diodes of the HF switch rectify the apply HF power and generate a proportional direct voltage.
