Since the radome 130 has an arch shape and both ends of the substrate 110 adjacent to the arch pins of both ends of the radome 130 are used for being connected to the vehicle body 210, the radome 130 positioned on the upper portion of the substrate 110 can have an arc profile corresponding to the top of the vehicle body 210, and the overall shape of the vehicle body 210 can be maintained to the maximum extent.
In addition, the first antenna array 140 and the second antenna array 150 are respectively disposed on two sides of the vehicle body 210, and the control module 120 is centrally disposed at a position higher in the middle of the vehicle body, so that the layout is reasonable, and the first antenna array 140 and the second antenna array 150 have corresponding isolation degrees.
Further, referring to fig. 3-5 in combination with fig. 1 and 2, in this embodiment, in order to ensure normal operation of all devices of the phased array terminal 100, efficient heat dissipation is also important, and the conventional heat dissipation method mainly depends on forced air cooling, which can effectively ensure heat dissipation efficiency, but brings problems of noise, power consumption, water resistance, and reliability. Therefore, in this embodiment, based on the above structure, in order to further improve the heat dissipation efficiency of the phased array terminal 100, the phased array terminal 100 may further include a heat exchange module 160;

Therefore, the invention can keep the integral shape of the car body 210 to the maximum extent by adopting the mode of integrating the phased array terminal 100 with the car body 210, and simultaneously considers the characteristic of lightness and thinness of the phased array terminal 100, the whole terminal is embedded between the top of the car body 210 and the roof trim panel 214, no space is occupied inside the car body 210, so that the phased array terminal 100 is perfectly integrated with a locomotive, and because the phased array terminal 100 is completely positioned inside the locomotive, all cables can be arranged and installed through the roof trim panel 214 while avoiding excessive holes on the car body 210, no cables are exposed outside, thereby improving the waterproof performance of the phased array terminal 100 through the mode;
in addition, because heat exchange module 160 and radome 130 set up side by side with heat exchange module 160, and one side of heat exchange module 160 and one side butt of radome 130, and then can avoid appearing the condition of leaking because of appearing the clearance between heat exchange module 160 and the radome 130.

The radome 130 is made of a honeycomb plate, and the surfaces of the radome 130 and the heat exchange cover 161 facing away from the substrate 110 are provided with hydrophobic coatings.
From this, such mode of setting, the drain tank of flowing to automobile body 210 top both sides that makes the rainwater can be smooth, nevertheless agree with in order to make radome 130 and the original structural shape of roof, arched radome 130 inclination is less, can't guarantee that all rainwater all flow away smoothly, arched radome 130 also can cause great performance loss simultaneously, in order to compromise and solve above problem, use loss is little on radome 130's material selection, intensity is good, light in weight's combined material's honeycomb panel, low-loss paint is chooseed for use to surface protection material, the hydrophobic coating of surface coating low-loss, the index decline problem that ponding and radome 130 caused can be solved to this scheme.
Based on the above, referring to fig. 1-5, in the present embodiment, since the frame 212 and the roof skin 213 are made of metal and have good heat conduction characteristics and heat exchange surfaces, high performance interface materials are disposed on the contact surfaces of the substrate 110 and the heat exchange module 160 with the frame 212 and the roof skin 213, respectively, so as to effectively conduct part of heat to the vehicle body 210 and dissipate heat.
