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: 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: Sidelobe suppression methods and systems for use in processing radar video streams generated by rotational radar antenna scanners. The sidelobe suppression methods function in parallel with traditional Sensitivity Control (SC) processing by selectively reducing sensitivity where necessary depending on sidelobe suppression schemes that can be either directional, omni-directional (non-directional), or a combination of these.

Abstract: Various implementations described herein are directed to adaptive frequency correction for pulse compression radar. In one implementation, a method may include generating a first transmission signal using a first direct digital synthesizer of a pulse compression radar system based on frequency sweep coefficients. The method may also include comparing a frequency of the first transmission signal at a feedback loop of a phase locked loop circuit and a frequency of an ideal waveform signal. The method may further include generating adaptive frequency coefficients based on the comparison, where the adaptive frequency coefficients are configured to compensate for a difference between the frequency of the first transmission signal at the feedback loop and the frequency of the ideal waveform signal. The method may additionally include generating a compensated transmission signal using the pulse compression radar system based on the adaptive frequency coefficients and the frequency sweep coefficients.

The system further includes a Radio Frequency (RF) power amplifier for amplifying the signals shaped by the amplitude modulator, an RF power detector for measuring power levels of the signals amplified by the RF power amplifier, and a pre-distortion coefficient generator for adjusting the measured power levels using power detector calibration coefficients that correspond to the RF power detector.
