Abstract: An example sonar transducer assembly is provided including at least one transducer element and a flexible printed circuit board (PCB) including at least one set of electrical connections for the at least one transducer element. The electrical connections include flex tabs configured to flex out of a PCB plane. The sonar transducer assembly also includes a support structure including an aperture for the at least one transducer element. The support structure is configured to support the body of the PCB, allow flexion of the flex tabs into the aperture, and retain the at least one transducer element in the at least one aperture. The transducer element is installed in a direction that is perpendicular to the PCB plane causing the flex tabs to flex outwardly from the PCB plane, thereby creating an elastic force of the flex tabs applied against opposing ends of the at least one transducer element.

Abstract: A system, computer-readable medium, and method for receiving reflected signals. In one implementation, the system includes a receiver, a pulse compressor, a framer, and a frame generator. The receiver receives the reflected signals. The pulse compressor compresses the reflected signals and the framer interprets the reflected signals. The frame generator combines one or more modified frames associated with the reflected signals.

Abstract: Various implementations described herein are directed to frequency correction for pulse compression radar. In one implementation, a method may include generating a first transmission signal using a pulse compression radar system based on an ideal waveform signal. The method may also include measuring a frequency of the first transmission signal at an output of a transmitter module. The method may further include comparing the measured frequency of the first transmission signal and a frequency of the ideal waveform signal. The method may additionally include generating pre-distortion coefficients based on the comparison, where the pre-distortion coefficients are configured to compensate for a difference between the measured frequency of the first transmission signal and the frequency of the ideal waveform signal. In addition, the method may include generating a compensated transmission signal using the pulse compression radar system based on the pre-distortion coefficients and the ideal waveform signal.

Abstract: Various implementations described herein are directed to multiple ranges for pulse compression radar. In one implementation, a method may include transmitting a first burst for a first range using a pulse compression radar system, where the first burst comprises one or more first pulse signals. The method may also include transmitting a second burst for a second range using the pulse compression radar system after transmitting the first burst, where the second burst comprises one or more second pulse signals. The method may further include repeating a transmission of the first burst using the pulse compression radar system after transmitting the second burst.
