摘要： A frequency conversion beam squint correction method of an active phase array antenna system including a plurality (m) of beamforming units configured of an antenna, a first amplifier, a phase shifter, a variable attenuator, and a second amplifier, the method includes the steps of: adjusting a delay time of an applied RF signal by arranging m/2 true time delays (TTDs) for every two adjacent beamforming units; and converting the frequency of the RF signal by mixing the RF signal transferred to each of the m/2 true time delays and a local oscillation signal using a mixer.

摘要： The present method and system relates to the determination of elevation angles for the case in which more than one target object is situated within a radar cell. Through the estimation according to the present invention of the elevation angles in multi-target scenarios, even in such cases both azimuth angles and elevation angles can be determined, and a reliable classification of the respective target objects can then take place. The present system also relates to a motor vehicle having a radar system that includes an azimuth and elevation angle estimation method and system.

摘要： The present invention provides an amplitude comparison monopulse radar system. The system comprises a beam forming network for coupling to the phased array antenna. The beam forming network is adapted to change the phase delays between the antenna elements in a phased array antenna such that the monopulse radiation pattern is scanned over an angular range through space.

摘要： Systems, methods, and devices relating to radar and radar-based applications. A number of comparators are coupled in parallel with each comparator comparing an incoming signal and a predetermined value. If the predetermined value is exceeded by the incoming signal, the comparator output is set to trigger a flip flop. The predetermined value changes with each comparator and, with the signal being the radar reflection from a radar pulse, this allows for the detection of the peak value of the incoming signal. The circuit may be extended so that the output of the comparator which is triggered by the highest peak from the incoming signal is latched. Other variants include being able to count the clock cycles before the highest peak is detected within the range cell.

摘要： A radar sensor for vehicles, including a group antenna, having a linear array of antenna elements, a feed unit for feeding transmission signals having a settable phase relationship into the antenna elements, a control unit controlling the feed unit, and an evaluation device evaluating received radar echoes and angle-resolving locating of objects. The group antenna includes at least two non-interleaved subgroups, the feed unit supplies in-phase transmission signals to the elements, while the transmission signals for the various subgroups have a settable phase difference, the control unit periodically changes the settable phase difference so that the transmission signals have a base phase difference in one measuring cycle and a phase difference in another measuring cycle which differs by a fixed absolute value from the base difference. The control unit sets the base difference based on levels of the received radar echoes to maximize the level difference between the measuring cycles.
