摘要： The present disclosure relates to a vehicle radar system (3) comprising a main control unit (38), a first radar sensor arrangement (4a) and a second radar sensor arrangement (4b), separated by a certain distance (d) and comprise a corresponding transmitter and receiver antenna arrangement (10a, 10b; 13a, 13b). Each receiver antenna arrangement (13a, 13b) has a corresponding receiver antenna radiation beam (47a, 47b) with a corresponding beam pointing azimuth angle (ϕ 1 , ϕ 2 ) relative a forward direction (F) in a corresponding maximum gain extension (46a, 46b). The maximum gain extension (46a, 46b) converge for beam pointing azimuth angles exceeding 0°. Each radar sensor arrangement (4a, 4b) is arranged for generating, transmitting and receiving radar signals (6a, 6b) in radar cycles. The radar signals (6a, 6b) are transmitted during a common time period for a major part of each radar cycle, where information regarding the time for transmission of each plurality of radar signals (6a, 6b) is obtained for each radar sensor arrangement (4a, 4b).

摘要： The invention relates to a novel system for measuring short distances using the propagation time of radio, sound, or light signals between at least one request unit and a transponder. An interference with the response signal of the transponder due to the request signal is eliminated by means of a highly precise delay of the request in the transponder. The delay is implemented with the required degree of precision with crystal accuracy in that the delay is carried out in a digital or analog register line, the register clock of which is kept in phase synchronization with the request signal such that the request signal is variably delayed in the request unit, and the delay is adapted using the detectable jump of the total propagation time, i.e. round trip, by a register clock period at the synchronization time preferably using a binary search.

摘要： An apparatus and method for enhanced calibration of radar at the module level supports dual polarization and array calibration and alignment without the use of external test equipment. Utilizing a delay line, loop back capability at the module level allows existing receiver exciter subsystem to be used for calibration. This approach eliminates the need for manual array calibration using external RF monitor subsystem or external test antennas.

摘要： A conventional signal generating circuit has a problem of being unable to compensate for an error of a chirp signal when V-F characteristics of a VCO change suddenly owing to disturbance. A signal generating circuit of the invention includes a control voltage setting unit (CVSU) configured to set a control voltage for a chirp signal using voltage-frequency characteristics indicating characteristics of an output frequency versus voltage; a VCO configured to alter the frequency of its output signal by the control voltage; a quadrature demodulator configured to perform quadrature demodulation of the output signal of the VCO to generate an inphase signal and a quadrature signal orthogonal to each other; and a frequency detector configured to detect the frequency of the output signal of the VCO on the basis of the inphase signal and quadrature signal. The CVSU corrects the control voltage by using the voltage-frequency characteristics derived from relationships between the control voltage and the frequency of the output signal of the VCO. The VCO generates the chirp signal based on the control voltage corrected by the CVSU.

摘要： A pulsed radar method of sensing or measuring a product material in a storage tank. A plurality of waveform types are automatically selected based on a power limitation. The pulsed radar signal is transmitted by a programmable transmitter (190) to the product material, wherein the pulsed radar signal is reflected or scattered by the product material to provide a radar signal during an interval of time including a target signal. An initial gain or attenuation is automatically set for a programmable receiver (150). The programmable receiver receives the radar signal including the target signal during the interval of time, and the target signal is signal processed using a lower attenuation setting as compared to the initial gain or attenuation to determine at least one parameter associated with the product material. The transmitted and received radar signal can also be adjusted according to the measured SNR.

摘要： A pulse compression radar for performing pre-distortion is provided, which has a configuration simplified in circuit structure. A radar apparatus (pulse compression radar) 1 includes an antenna 10 configured to externally transmit a transmission signal transmitted by a power amplifier 16 and receive a reflection signal caused thereby as a reception signal. The radar apparatus 1 includes a reception circuit 41 configured to propagate this reception signal to a radar image creating module 26. The radar apparatus 1 corrects beforehand, by utilizing the transmission signal (feedback signal) transmitted from the power amplifier 16, a transmission signal to be inputted into the power amplifier 16 so as to cancel distortion of the transmission signal caused by amplification effect of the power amplifier 16. Further, a circuit where the reception signal passes and a circuit where the feedback signal passes share a part of each other.
