The array errors comprise: element phase and amplitude, element positions, defective elements, and structural deformation of the aperture. One of the unique capabilities of APAS is the synthesis of low sidelobe tapers for both sum and difference patterns including multiple sector nulling. Amplitude-only synthesis is supported as well as phase-only and complex weighting. Another distinct feature is the very fast calculation and subsequent processing of the 2D array far-field.
This type of computation is carried out in almost real time time. A far-field calculation including its subsequent processing involving x far-field directions, is done within 0. The subsequent far-field processing comprises array directivity, 3 dB beamwidth, peak sidelob level, average sidelobe level and beam efficiency. In this way APASplus can be become part of a phased array radar system simulator.
You can view code for each plot, and use it in your own project. The Sensor Array Analyzer app lets you examine important properties of a phased array such as response and geometry. Apply tapering and model thinning on different array configurations. It also demonstrates how to create arrays with different element patterns.
Use pilot calibration to improve the performance of an antenna array in the presence of unknown perturbations. A self calibration procedure based on a constrained optimization process. Sources of opportunity are exploited to simultaneously estimate array shape uncertainties and source directions.

Phased Array Design and Analysis Antennas, microphones, and sonar transducers, array geometries, polarization, transmitters, receivers, and acoustic transducers.
Phased arrays have three main advantages over individual elements: Improved spatial resolution — view more detailed resolution when localizing and imaging a target. Manual steps involving working with an Excel spreadsheet to accomplish length matching is completely eliminated via this automation.
Possibility for human error eliminated through automatic match verification up to 8 decimal places. Arraying and auto-modifying cells while maintaining only one version. Documentation is completely automated. Fabrication document with all levels shown can be created automatically. Multiple levels of Assembly drawings can be created automatically.
Full CAM output can be provided to speed time to market. Software automation for an assembly line. Data for test requirements. Our hierarchical schematic system can easily capture and display your complete design. Schematics with LVS checking assures first run success. We can write code to auto-draw the phased array portion of the schematic. Hierarchy makes design easy to understand.
CDS is the only EDA company that provides an advanced and intelligent level of custom enhancements with complete support. Customization of EPD software comes at a fraction of the cost that other vendors would charge. Designers can create their own customizations.
Extremely cost effective when compared with other tools.
