摘要： The disclosure provides a radar apparatus, a signal processing circuit, and a signal processing method for radar apparatus. The radar apparatus includes a frequency synthesizer, a signal generator, and a transmitting front-end circuit. The frequency synthesizer generates a carrier signal. A frequency of the carrier signal changes with time within a sweep period of the carrier signal, and the carrier signal includes a frequency raising section and a frequency decreasing section. The signal generator generates a shaping signal. The shaping signal includes two sections. The two sections have different amplitudes. One of the two sections corresponds to a turn-around section between the frequency raising section and the frequency decreasing section. The transmitting front-end circuit is coupled to the frequency synthesizer and the signal generator and generates a transmitting signal according to the carrier signal and the shaping signal. In this way, the spurious peak on the spectrum is reduced.

摘要： A method of measuring phase noise (PN). A PLL frequency synthesizer is provided including a first phase frequency detector (PFD) receiving a reference frequency signal coupled to a first charge pump (CP) coupled to a VCO having an output fedback to the first PFD through a feedback divider that provides a divided frequency signal to the first PFD which outputs an error signal, and PN measurement circuitry including a replica CP coupled to an output of a second PFD or the first PFD. The error signal is received at the replica CP or the divided and reference frequency signal are received at the second PFD, wherein the replica CP outputs a scaled phase error current which is current-to-voltage converted and amplified to provide an amplified phase error voltage, and digitized to provide a digital phase error signal. The digital phase error signal is frequency analyzed to generate a PN measurement.

摘要： A method for separating large and small targets from noise in radar IF signals, according to which a receiver receives, echo signals that are reflected from targets of different size (such as walls or ground), in response to the transmission of chirp FMCW radar signals, modulated (e.g., using Linear Frequency Modulation) in a predetermined modulation speed for a predetermined duration. The echo signals are down-converted by mixing them with the transmitted signal, to obtain received Intermediate Frequency (IF) signal, which is then sampled both in phase (I-channel) and in quadrature phase (Q-channel). The received IF signal passes a Fourier transform, to obtain power spectral components that belong to a relevant frequency domain, associated with an echo signal reflected from a real target, along with corresponding power spectral components that belong to an irrelevant, opposite frequency domain. The noise distribution and level in the relevant frequency domain is calculated by estimating the noise level in the irrelevant frequency domain and targets represented by a set of consequent relevant frequencies are detected by comparing the power spectral component at each relevant frequency to the calculated noise level and identifying power spectral components with likelihood, which is above a predetermined threshold.

摘要： A waveguide device includes: an electrically conductive member having an electrically conductive surface; a waveguide member having an electrically-conductive waveguide face of a stripe shape opposing the electrically conductive surface, the waveguide member extending along the electrically conductive surface; and an artificial magnetic conductor extending on both sides of the waveguide member. The waveguide member has a bend at which the direction that the waveguide member extends changes. A waveguide which is defined by the electrically conductive surface, the waveguide face, and the artificial magnetic conductor includes a gap enlargement where a gap between the electrically conductive surface and the waveguide face is locally increased. In a perspective view along a direction perpendicular to the electrically conductive surface, at least a portion of the bend has an overlap with the gap enlargement.

摘要： Systems and methods of operating an interference prevention system in a radar altimeter are provided. A method includes generating integer values with at least one pseudorandom noise sequence generator. The generated integer values are used as indexes to select at least one of start frequencies and stop frequencies from at least one frequency table for frequency modulated continuous wave (FMCW) ramps for a generated radar signal. The selected at least one of the start frequencies and the stop frequencies is provided to a frequency synthesizer. The at least one of start frequencies and the stop frequencies are used in generating transmit frames of the radar signal with the frequency synthesizer.
