    Abstract: Techniques are disclosed for systems and methods to provide transmission signal shaping for transmission signal-based sensor systems, such as radar and/or sonar sensor systems. A low noise signal shaping transmitter includes a digital to analog converter configured to convert a digital shaping control signal to an analog shaping control signal, a signal shaping circuit configured to convert the analog shaping control signal into a shaped voltage, and a power amplifier configured to provide a shaped transmission signal based on the shaped voltage and a digital transmission control signal. Each element of the transmitter may be formed from relatively slow switching analog and/or digital circuitry components. Resulting shaped transmission signals may be used to excite radar antennas, sonar transducers, sound cells, and/or other elements of sensor systems.

    Abstract: Methods, apparatuses, and computer program products are provided for producing a 3D image of an underwater environment. 2D sonar return data that defines an angle and distance value may be taken from a theoretical 2D slice of the underwater environment. Multiple sets of 2D sonar return data are taken from corresponding 2D slices of the underwater environment during travel. The multiple sets of 2D sonar return data can be inputted into a 3D point cloud/matrix based on the distance value and angle and the corresponding 2D slice associated with each sonar return. The 3D point cloud/matrix can then be processed to determine a cluster of sonar returns that correspond to the bottom surface. Additional filtering may be performed and the bottom surface can be reconstructed to form a 3D image for display to a user.

The sonar system may include a housing having a transmit transducer that may transmit sonar pulses into the water. The system may include at least one transducer array in the housing that receives first, second, and third sonar returns with first, second, and third transducer elements and converts the first, second, and third returns into first, second, and third sonar return data.

    Abstract: Frequency-steered acoustic arrays transmitting and/or receiving multiple, angularly dispersed acoustic beams are used to generate 2D and 3D images. Input pulses to the arrays are generally non-linear, frequency-modulated pulses. Frequency-steered acoustic arrays may be provided in one-dimensional linear and two dimensional planar and curvilinear configurations, may be operated as single order or multiple order arrays, may employ periodic or non-periodic transducer element spacing, and may be mechanically scanned to generate 2D and 3D volumetric data. Multiple imaging fields of view may generated in different directions by switching the polarity of phase-shifted array transducer elements. Multiple frequency-steered arrays arranged in an X-configuration provide a wide, contiguous field of view and multiple frequency steered arrays arranged in a T-configuration provide orthogonally oriented fields of view. Methods and systems for operating acoustic arrays in a frequency-steered mode in combination a mechanical beam steering mode, electronic time-delay and phase shift beam forming modes, and phase comparison angle estimation modes are also provided.
