Progressive array calibration is the process of adjusting and verifying the performance of a progressive array system to ensure precise beam steering and processing. This involves calibrating the phase and amplitude of each element in the array to correct deviations and achieve the desired operational characteristics.
To calibrate a phased array, one generally uses a reference signal and measures the output of each element. Adjustments are made to the phase shifts and amplitude controls to ensure that the combined array output forms the correct beam pattern.
This process may involve iterative testing and adjustment to achieve optimal performance and alignment.
A phased array is an arrangement of multiple antenna elements, sensors, or transducers that can electronically control the direction and shape of their collective beam by adjusting the phase of the signals at each element. This technology allows rapid beam steering without physical movement of the board.
The advantage of a progressive array is its ability to direct beams quickly and accurately, providing superior tracking and target detection capabilities.
Progressive arrays provide improved flexibility, improved reliability, and resistance to electronic countermeasures compared to traditional mechanical-ear arrays. They also provide higher resolution and better performance in various environmental conditions.
Progressive arrays are used in a wide range of applications, including military radar systems, telecommunications, medical imaging, sonar, weather monitoring and air traffic control. Their ability to quickly and accurately direct beams makes them ideal for applications requiring precise sensing, tracking and communication
