Problems solved by technology

At present, high-density integrated active phased array T / R components are widely used in the form of hard connection, which has the risk of extrusion damage caused by assembly and thermal stress
Moreover, due to the high integration, the heat flux distribution is uneven, and the temperature gradient is large, which affects the long-term stability and reliability of the system
In addition, in order to meet the designed array weighting value, the amplitude of different RF channels needs to be trimmed, so the dynamic range of the feeding amplitude will be lost, which is not conducive to the weighting effect of amplitude weighting and large dynamic range

Embodiment

[0116] Embodiment: Arranging T / R components of the shared transceiver array with reference to the method of the present invention.

[0117] step one:

[0118] The size of the array is M×N (M=20, N=20), the size of the radio frequency channel connected to each T / R component and the antenna unit is P×Q (P=1, Q=4), and the total required T The number of / R components is S×T (S=20, T=5). The maximum gear attenuation of the attenuator of the T / R component is A' max =15.5dB, the attenuation step is ΔA=0.5dB. The dynamic range of the received amplitude weighted value D R =15.5dB, the dynamic range of the emission amplitude weighted value D T = 0dB. due to D R ≥D T , Amp is the weighted value of the receiving array (such as image 3 shown). The maximum amplitude attenuation of the entire array obtained by optimization is A max = 15.5dB.

[0119] Step two:

[0120] The entire array area corresponding to the amplitude weighted value Amp is divided into 20*5 T / R components co...

Abstract

The invention provides a high-density integrated active phased array T / R assembly arrangement method based on mechanical size, electric property and heat consumption. The method comprises the implementation steps that 1, a T / R assembly arrangement area is divided into different amplitude weighted sub-areas according to amplitude weighted values; 2, a 0 attenuation area, a maximum attenuation areaand an interchange area are determined, T / R assemblies respectively arranged in the 0 attenuation area and the maximum attenuation area are determined, and the T / R assemblies in the corresponding areas are arranged; 3, the interchange area is divided into a small attenuation interchange area, a large attenuation interchange area and a full interchange area, and the remaining to-be-arranged T / R assemblies are arranged in the three areas according to the principle that the internal heat consumption is less than the external heat consumption; and 4, the positions of the T / R assemblies are adjusted according to the total thickness of each column of the T / R assemblies along the extrusion direction, so that the total thickness of each column is consistent. The reliability of the phased array system can be improved, the heat flux density distribution is improved, and the dynamic range of amplitude distribution is widened.

Description

technical field [0001] The invention belongs to the technical field of antennas, can be used for the arrangement of high-density integrated active phased array T / R components, relates to a method for arranging phased array T / R components, and specifically relates to a high-density integration based on mechanics, electricity and heat Active phased array T / R component arrangement method. Background technique [0002] With the development of microwave technology and the continuous improvement of requirements, the scale of active phased array array is getting larger and higher, and the integration level is getting higher and higher. At present, high-density integrated active phased array T / R components are widely used in the form of hard connection, which has the risk of extrusion damage caused by assembly and thermal stress. Moreover, due to the high integration, the heat flux distribution is uneven and the temperature gradient is large, which affects the long-term stability a...
