Abstract

The invention relates to an X-band dual-polarization rapid scanning phased array weather radar, which includes a dual-polarization antenna feed system, a transmitting system, a receiving system, a digital processing system, a frequency source, a servo system and a terminal computer. The invention has the advantages of reducing the number of transmission channels and increasing the transmission power of a single channel to perform pitch-to-wide beam transmission and narrow beam reception, so that the radar detection efficiency can be significantly improved without reducing the radar detection capability. Through the digital beam forming technology, the narrow beam detection of the elevation angle can be completed in one reception, and the echo calculation of the entire elevation direction can be completed without sacrificing the radar receiving ability. Adopting a new system of separating transceivers reduces the number of transmitting channels, reduces the difficulty of receiving and transmitting channel structures, and reduces the number of related components such as circulators, thereby reducing system development and production costs.

Description

technical field [0001] The invention relates to the field of phased array antenna technology and transceiver systems, in particular to an X-band dual-polarization fast scanning phased array weather radar. Background technique [0002] Phased Array Radar (Phased Array Radar, PAR) is a phase-controlled electronically scanned array radar. A large number of individually controlled small antenna units are arranged into an antenna array. Each antenna unit is controlled by an independent phase-shift switch. By controlling each antenna The phases emitted by the units can be used to synthesize beams of different phases. However, the current phased array radars often cannot take into account the fast scanning and high detection capabilities at the same time, and the overall system complexity is high, and the stability and anti-interference ability are weak; therefore, how to make the phased array radar take into account the wide beam High efficiency in scanning mode and high detectio...
