Abstract

Digital array radar has many advantages, such as large gain, high reliability, extended dynamic range and airspace anti-interference. However, due to the limited development of digital array transceiver components, there are still some difficulties to realize the full digital array radar. This paper proposes a digital array radar applied to the fighter, which realizes the frequency transformation, filtering and sampling at the sub-array level. The signal is transmitted to the beam synthesis module through optical fiber, and separately generate the dots and navigation tracks. The key points of delay, transmission and dynamic range in digital array system design are presented. Finally, the test and calibration methods of digital array channels and the opportunities and challenges of digital array system design are discussed. The radar system scheme of sub-array-level digitization takes into account many factors, such as applicability, anti-interference and cost.It meets the tactical requirements of the current stage.
