  • Patent number: 9684070
    Abstract: A radar apparatus measures at least one characteristic of at least one object. A sweep generator generates a sweep signal to modulate an oscillator to generate a varying frequency signal. A transmitter transmits the varying frequency signal as a radar signal. A receiver receives a reflected radar signal to produce a received signal using the varying frequency signal. A compensation signal memory holds a previously stored compensation signal. A compensation circuit compensates the received signal based on the previously stored compensation signal to produce a compensated received signal. A quiet switch quiets the reflected radar signal and determines the previously stored compensation signal, during calibration of the radar apparatus, and the received signal is written into the compensation signal memory. Switched loads can be used to quiet the reflected radar signal. For field calibration, the compensated signal can be adjusted but not necessarily written back into the compensation signal memory.

  • Patent number: 9684073
    Abstract: A radar apparatus includes an antenna section that transmits and receives a radar wave, a high-frequency circuit section that handles a high-frequency signal, and a low-frequency circuit section that handles a low-frequency signal. The low-frequency circuit section is arranged on a major face of a main printed board. The high-frequency circuit section and the antenna section are arranged respectively on first and second faces of a secondary printed board. Moreover, the secondary printed board is mounted to a space on the major face of the main printed board which is not occupied by the low-frequency circuit section. Consequently, it becomes possible to use the high-frequency signal by using an insulating material, which is necessary for suppression of dielectric loss, only for the secondary printed board.

  • Patent number: 9671493
    Abstract: Described is system for optimizing visual inspection of radar targets. The system detects radar hits with a radar system comprising radar and a radar-cued camera. The camera has a current state comprising a current slew position and a current zoom level. The radar hits are stored, and a set of metrics are determined for each radar hit. A track value (TV) metric is determined that combines the set of metrics for each zoom level of the camera. The camera sends a set of commands based on the TV metric, such that the camera slews from the current state to a new state. The new state is a position of a radar hit with the largest TV metric and a corresponding zoom level. Given the new state, an image is captured and processed to generate captured tracks. The current state of the camera is updated to reflect the new state.

  • Patent number: 9651652
    Abstract: Systems and methods for cancelling interference while performing direction/location. A combined signal of interest plus interference signal may be received. A copy or sample of the interference signal may be determined. The interference signal and the combined signal of interest plus interference signal may be converted to the optical domain. The interference signal may be optically phase shifted by ?180 degrees, which may result in an optically inverted interference signal. The optically inverted interference signal may be variably optically attenuated and/or variably optically time delayed. As a result, interference cancellation of the interference signal from the combined signal of interest plus interference signal may be achieved, resulting in 50 dB or more of cancellation of the interference signal. Direction and/or location finding techniques can be applied to received signals during and/or after interference cancellation.

  • Patent number: 9603555
    Abstract: A motion/vibration detection system and method therefore are provided. The system includes a transmitter and a receiver. The transmitter includes a transmit/receive antenna unit and a first oscillator. The receiver includes a receiving unit and a demodulation unit. The transmit/receive antenna unit receives an output signal from the first oscillator and transmits a detection signal. The detection signal is reflected from at least one object under detection into a reflected detection signal, which is received by the transmit/receive antenna unit. The transmit/receive antenna unit injects the reflected detection signal into the first oscillator and accordingly the first oscillator is under a self-injection locking mode. The receiving unit receives the detection signal. The demodulation unit demodulates the detection signal received by the receiving unit into a baseband output signal, to extract at least one motion/vibration information of the objection under detection.
