摘要： A distance measurement arrangement (DDM) provides a distance indication (DV) on the basis of a delay between an electromagnetic signal (TB), which is transmitted in a transmission mode, and a reflection (RB) of the electromagnetic signal, which is received in a reception mode. The distance measurement arrangement includes an antenna module (AM) comprising a plurality of antennas for transmitting the electromagnetic signal (TB) and for receiving the reflection (RB) thereof. A beam-forming module (BF) defines respective magnitude and phase relationships with respect to respective antennas so as to cause the antenna module (AM) to provide a directional antenna pattern in at least one the two aforementioned modes. Preferably, a beam-forming and steering control module (BC) controls the respective magnitude and phase relationships as a function of a direction command (DIR). A 3-D picture can be formed by applying respective direction commands (DIR) so as to obtain respective distance indications (DV) for respective portions in a two-dimensional picture.

摘要： The present invention relates to a transmission apparatus having at least two transmission branches for transmitting respective transmission signals at substantially same frequencies, and to a method of controlling such a transmission apparatus. A first oscillator circuit (62) is provided for generating a first signal at a first frequency to be used in a first transmission branch. Additionally, a second oscillator circuit (64) is provided for generating a second signal at a second frequency to be used in a second transmission branch, the second frequency being different from the first frequency. To enable transmission of the transmission signals at said substantially same frequencies, at least one frequency divider or multiplier (72, 74) is provided for dividing or respectively multiplying at least one of said first and second frequencies by a respective predetermined factor. Thereby, the first and second oscillator circuits can be operated at different frequencies, so that mutual coupling can be reduced.

摘要： A system comprises a plurality of object detection modules (SC3, SC4). An object detection module detects an object from a radiation in a particular wavelength range. The system is operable to cause an object detection module (SC4) to operate in a probing master mode (PMM). In this mode, the object detection module (SC3) produces a probing radiation (PR) in the particular wavelength range. Another object detection module (SC3) is caused to operate in a probing slave mode (PSM). In this mode, the other object detection module (SC3) provides an acknowledgment (ACK) in response to receiving the probing radiation (PR).
