摘要： The disclosure relates to a radar apparatus of the type which comprises a transmitter which substantially continuously transmits a modulated carrier wave signal, and a receiver for receiving the carrier wave signal (the echo signal) reflected against an object, and in which the carrier wave signal is modulated with an encoding signal in which one bit in the code is of a duration which is several times longer than the period time of the carrier wave signal, and in which the code of several bits forms a block which is characterized by modulation of a carrier wave at constant frequency. Furthermore, the frequency of the carrier wave is changed between the blocks, so that the transmitter transmits one block with a carrier wave frequency which is different from the carrier wave frequency or frequencies which the receiver is set to receive. The apparatus includes means for dividing code blocks of the same frequency into a number of subunits, for example eight in number, in which each subunit is first correlated individually, and thereafter doppler analysis is carried out on the subunits of the block.

摘要： A distance measuring method and apparatus in which first and second pseudo random signals which are the same in pattern but slightly different in period are generated to obtain a correlation output of the first and second pseudo random signals before transmission thereof as a reference correlation output, and the first pseudo random signal is directly transmitted toward a target or alternatively a carrier wave is modulated by the first pseudo random signal and transmitted toward the target. A correlation output of the signal reflected and received from the target and the second pseudo random signal is detected and the distance to the target is measured from the time interval between the reference correlation output and the received correlation output. Alternatively, the modulated carrier wave reflected and received from the target and the second pseudo random signal are subjected to correlation processing to detect a correlative modulated carrier wave and the correlative modulated carrier wave is subjected to orthogonal detection by a reference carrier wave thereby obtaining a target detection output. Then, the distance to the target is measured from the time interval between the reference correlation output and the target detection output.

摘要： A spread spectrum system in which two sub-carrier signals symmetrically disposed about a carrier frequency extracted by phase-locked loops (44 and 45) are subjected to phase reversal keying by a pseudo-random binary sequence defining a chip rate to produce a spectrum of which the power distribution is concentrated away from the carrier frequency towards sidebands associated with the chip rate.

摘要： This document describes techniques and systems to enable a radar system to jointly detect Do A and DoD angles in multipath scenarios. In some examples, an automotive radar system includes one or more processors. The processors obtain electromagnetic (EM) energy reflected by objects and generate, based on the reflected EM energy, a two-dimensional (2D) data matrix. The 2D data matrix has a number of rows corresponding to the number of antenna elements in a transmitter array and a number of columns corresponding to the number of antenna elements in a receiver array. Using the 2D data matrix, the processors can determine DoA estimates and DoD estimates in both monostatic and bistatic reflection scenarios. By comparing the DoA estimates to the DoD estimates, the processors determine angles associated with the objects with improved angular resolution and reduced cost.

摘要： A dual-mode analog beam forming (ABF) circuit (104) for a communication unit (100) that includes a plurality of individual antenna elements (102), wherein the dual-mode ABF circuit (104) comprises at least one of: a RF splitter (212, 512) for splitting an input modulated RF signal into a plurality of modulated RF signals that are applied to respective antenna elements of the plurality of individual antenna elements and/or a RF combiner (232) for combining a plurality of input modulated RF signals into a modulated RF signal. A plurality of phase adjustment elements is respectively coupled to a beam-index LUT (117) and a phase of each phase adjustment element is individually controlled by the beam-index LUT. The beam-index LUT is configured to support antenna beam forming of two modes of operation, comprising an analog beam forming communication mode of operation; and a ST-CDMA-MIMO radar mode of operation.
