Abstract

The invention belongs to the field of radar technologies and discloses a dual-polarization radar. The dual-polarization radar comprises a transmitting module, a receiving module, a receiving and transmitting switching module, a first polarization direction antenna and a second polarization direction antenna, wherein the transmitting module is used for generating a pulse pair signal, and the pulsepair signal comprises a first pulse signal and a second pulse signal with different radio frequencies; the receiving module is used for receiving backscattered echo signals of the first pulse signal and the second pulse signal; the receiving and transmitting switching module is used for transmitting the first pulse signal to the first polarization direction antenna, transmitting the second pulse signal to the second polarization direction antenna and transmitting a first polarization direction echo signal and a second polarization direction echo signal to the receiving module; the first polarization direction antenna is used for transmitting the first pulse signal and receiving the first polarization direction echo signal; and the second polarization direction antenna is used for transmitting the second polarization pulse signal and receiving the second polarization direction echo signal. Through the dual-polarization radar, an alternate sending, simultaneous receiving and single-receiving-channel radar structure is realized, and the dual-polarization radar has good echo signal correlativity and monitoring precision.

Description

technical field [0001] The invention relates to the technical field of weather radar, in particular to a dual-polarization radar. Background technique [0002] Existing dual-polarization weather radars are mainly divided into: AHV system with alternate transmission and reception at the same time and SHV system with simultaneous transmission and reception at the same time. Among them, both the SHV and AHV systems need to set up two receiving channels, resulting in a relatively high architecture scale and complexity; at the same time, the equipment cost remains high. Especially for the multi-channel phased array radar, the scale, complexity and equipment cost are more obvious. Contents of the invention [0003] The invention provides a dual-polarization radar, which solves the technical problems of complex structure and large scale of the receiving module of the dual-polarization radar in the prior art. [0004] In order to solve the above technical problems, the present i...
