Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] A multi-section air stripline line feed network, including the first line feed network, the second line feed network, the third line feed network, the fourth line feed network, and the fifth line feed network; the first The section row feeder network, the second row feeder network, the third row feeder network, the fourth row feeder network, and the fifth row feeder network are connected by cables, and the overall size is smaller after the azimuth plane is folded. , to facilitate the miniaturization design of the radar.

[0015] Such as Figure 5 As shown, the line feed network of the present invention includes 36 output ports, the output power gradually increases from port 18 to port 1, and the output power gradually decreases from port 19 to port 36, and the output power from port 18 to port 1 and port 19 to port 36 The port output power is m...

Abstract

The invention relates to the technical field of radar antenna feeders, in particular to a segmented air strip line row feed network which is suitable for a one-dimensional phased array radar antenna feeder system. Problems that a single row feed network is heavy and an antenna array plane cannot be folded in the horizontal direction after array forming are solved in a segmented connection mode. According to the invention, after the row feed network is segmented and the cable is connected, the azimuth plane can still have the ultra-low sidelobe characteristic after the row feed network is connected with the antenna through optimization design.

Description

technical field [0001] The invention relates to the technical field of radar antenna feeders, in particular to a segmented air stripline feeder network, which is suitable for a one-dimensional phased array radar antenna feeder system. Background technique [0002] In one-dimensional phased array radar, line-feed network has a very wide range of applications. It distributes the power of the radar transmitter to each transmitting unit in a certain proportion, forms a specific shaped beam in the air, and satisfies the coverage of the specific airspace of the radar. Require. [0003] The line-feed network is formed by cascading multi-section power distribution networks. There are mainly three commonly used power distribution networks, coaxial cavity power distribution network, microstrip power distribution network and stripline power distribution network. The advantages of the microstrip power distribution network are small size and high isolation, and its disadvantages are sma...
