| description | A Frequency Diverse Array (FDA), developed innovatively based on phased array radar, can obtain an angle-range-time-dependent multidimensional transmit beampattern by modulating frequencies across different transmit antenna elements, which considerably increases the beam control ability and signal processing dimension. After joint transmit-receive processing, an FDA can be applied to various areas, such as multidimensional parameter joint estimation, mainlobe deceptive jammer suppression, ambiguous clutter suppression, and high-resolution and wide-swath imaging. This study investigates the waveform design and signal processing method of a multifunctional integrated system based on an FDA from the system level, with emphasis on new signal processing methods for integrated detection and estimation, integrated ambiguity resolution and jammer suppression, as well as integrated Synthetic Aperture Radar (SAR) imaging and moving target detection. Moreover, the application prospects of FDA multifunctional integrated systems are provided. |
