Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with specific embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, so they are only examples, and should not be used to limit the protection scope of the present invention.

[0028] The present invention is illustrated by the embodiment that each sub-array contains 8 T / R components, and the specific process is as follows:

[0029] The sub-array is mainly composed of 8 eight-channel T / R components 3, 1 signal generating and receiving module 4, 1 communication receiving module 5, and 1 fan 1 and air duct 2. Fans and air ducts are arranged on the top of the sub-array, and natural wind is used to dissipate heat from the lower modules through the air ducts. Eight T / R modules are arranged under the fans, signal generation and receiving modules are arranged under the T / R modules, and communication modules are arranged under the signal ...

Abstract

The invention relates to a simultaneous multifunctional phased array subarray, and belongs to the field of radar array planes. The simultaneous multifunctional phased array subarray mainly comprises an eight-channel T / R assembly, a signal generating and receiving module, a communication receiving module, a draught fan and an air channel. The subarray can realize simultaneous emission of multiple frequencies during emission, and realize simultaneous work of passive detection and communication measurement during receiving, and a multifunctional radar with the same function can be realized through simple sub-array splicing without redesigning an area array. And meanwhile, the multifunctional phased array subarray technology can powerfully support the work of the current simultaneous multifunctional phased array equipment, and the simultaneous multifunctional requirements of the equipment platform in the use process are met.

Description

technical field [0001] The invention relates to a phased array sub-array, in particular to a simultaneous multifunctional phased array sub-array. Background technique [0002] With the development of phased array equipment, it undertakes more and more functions, from traditional active and passive detection to communication, weather detection, etc., and its performance indicators such as bandwidth, power, sensitivity, etc. are also gradually improved. When the equipment platform requires multiple functions, if each function is equipped with a phased array equipment, it will cause a large amount of equipment and increase the cost. At the same time, the equipment is independent of each other and requires a large installation space, which can no longer meet the needs of multiple equipment platforms. function, high integration and high electromagnetic compatibility requirements, especially on airborne platforms, small surface carrier platforms, etc., it is difficult to install m...
