摘要： This application provides an information measurement method and an information measurement apparatus. The information measurement method includes: simultaneously transmitting a first measurement signal and a second measurement signal; receiving, as a first reflected signal, a signal obtained through reflecting the first measurement signal by a target, and receiving, as a second reflected signal, a signal obtained through reflecting the second measurement signal by the target; and calculating status information of the target based on a difference between the first measurement signal and the first reflected signal and a difference between the second measurement signal and the second reflected signal. Correspondingly, the information measurement apparatus is further provided. Implementing this application in the self-driving field can improve time utilization of environment perception, and can also improve transmit channel utilization.

摘要： A memory access unit (24; 74 1 ,...,74 m ) for handling transfers of samples in a d-dimensional array between a one of m data buses (27; 77), where m ‰¥ 1, and k*m memories (22 1 ,...,22 k ; 72 1 ,...,72 k*m ), where k ‰¥ 2, is disclosed. The memory access unit comprises k address calculators (28 1 ,...,28 k ; 79 1 ,...,79 k ), each address calculator configured to receive a bus address (A_B) to add a respective offset to generate a sample bus address (A_B') and to generate, from the sample bus address according to an addressing scheme, a respective address (A_1, ..., A_d) in each of the d dimensions for access along one of the dimensions from the bus address according to an addressing scheme, for accessing a sample. The memory access unit comprises k sample collectors (29 1 ,...,29 k ; 80 1 ,...,80 k*m ), each sample collector operable to generate a memory select (CS) for a one of the k*m memories so as to transfer the sample between a predetermined position in a bus data word and the respective one of the k*m memories. Each sample collector (29 1 ,...,29 k ; 80 1 ,...,80 k*m ) is configured to calculate a respective memory select in dependence upon the address in each of the d dimensions such that each sample collector selects a different one of the k*m memories so as to allow the sample collectors to access k of the k*m memories concurrently. A memory controller may comprise m memory access units (74 1 ,...,74 m ) for handling transfers of samples in a d-dimensional array between m data buses (77 1 ,...,77 m ) and k*m memories (71 1 ,...,71 k*m ).

摘要： A method for determining the position of a target is provided. In a phased array system (200), several emitted pulses of terahertz radiations are emitted from a phased array (204) (which has several transceivers (206-1 - 206-N) in consecutive cycles (typically). These emitted pulses are generally configured to be reflected by a target so as to be received by the phased array within a scan range (which includes a digitization window with several sampling periods). Output signals from each of the transceivers (206-1 - 206-N) are then combined to generate a combined signal for each cycle. The combined signal in each sampling period within the digitization window for emitted pulses is averaged to generate an averaged signal for each sampling period within the digitization window. These averaged signals are then digitized.

摘要： An in-phase/quadrature component (IQ) mixer (306) is configured to reject returns from a negative doppler shift swath in order to mitigate corruption of returns of a positive doppler shift swath. The mixer includes a sample delay element (330) which produces a quadrature component from the in-phase component of an input signal. Further included are a plurality of mixer elements (322, 332), a plurality of low pass filters (324, 334), a plurality of decimators (326, 336), and a plurality of all pass filters (328, 338) which act upon both the in-phase and quadrature components of the input signal. Also, a subtraction element (340) is included which is configured to subtract the filtered and down sampled quadrature component from the filtered and down sampled in-phase component.

摘要： A method and apparatus for preventing the occurence of range ambiguities and Doppler ambiguities in both a radar and sonar environment. A series of N pulses are produced, each of which contains a number of contagious subpulses. Each of the subpulses exhibits a different frequency than the remaining subpulses in that particular pulse. Furthermore, the order of appearance of the subpulses in each of the pulses is unique with respect to the remaining pulses in the series. A matched filter receiver (10) and Doppler processor (30) are used to provide auto correlations and cross correlations (R1-RN) to prevent the range ambiguities and Doppler ambiguities.

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 with constant frequency. Furthermore, the frequency of the carrier wave is changed between the blocks, so that the transmitter transmits one block at a carrier wave frequency which is different from the carrier wave frequency or frequencies which the receiver is set to receive. A received binary coded signal is, after A/D conversion (1), supplemented with an additional value which is the measurement value with reversed sign, the measurement value or measurement value with reversed sign, respectively, being, in each time step, fed to different range bins (3), where the range bins (3) receive a sequence of measurement values, and in which the given, transmitted code unambiguously determines, for each time step, to which range bin (3) the measurement value or measurement value with reversed sign, respectively, is to be fed, the integration of inputted values in a range bin (3) providing information on a possible target in this range bin.
