[0002] Radar antenna installation requires a base, and the existing technology generally uses a mobile radar vehicle or a fixed bracket for installation. However, in remote mountainous areas, radar installation is extremely inconvenient.

[0151] When the radar assembly 2 is in operation, the secondary radar 301 is activated.

[0152] A frame structure 303 located in the inner cavity of the mountain is provided on the auxiliary component 1;

[0153] The frame structure 303 is adapted to the space inside the mountain cavity;

[0154] A side beam 304 is arranged on the frame structure 303, and a suspended top beam 305 is arranged on the side beam 304, so as to realize bottom support without relying on the mountain, and at the same time, support the mountain to prevent collapse.

[0161] A radar antenna unit 200 is provided on the swing arm assembly 201;

[0162] The swing arm assembly 201 has an open state and a closed state.

[0163] In order to interfere with enemy detection, the secondary radar 301 simulates the appearance of the radar antenna section 200 of the primary radar station 302 .

[0164] In order to protect the main radar and reduce its loss, in non-wartime state, the secondary radar 301 is in operation; in wartime state, the radar antenna unit 200 is in operation.

[0165] In order to facilitate engineering operations in the mountains, a crane is installed on the suspended top beam 305 to assist in disassembling and assembling the radar antenna unit 200 .

[0166] In order to serve as a false target as a substitute, a dummy radar is set around the secondary radar 301.

[0167] like Figure 1 The radar concealed mountain operation engineering method of this embodiment preferably uses the above-mentioned equipment and method steps, mainly using the radar shelter auxiliary engineering system; the method includes non-wartime working steps and wartime steps;

[0168] In the non-wartime working procedure, the secondary radar 301 is activated; the main radar station 302 is in a closed state;

[0169] As a protection of the operation method, in the wartime step, the secondary radar 301 is started and the main radar station 302 is started intermittently; the main radar station 302 and the secondary radar 301 form a radar matrix.

The radar component 2 is convenient for transportation and installation by improving the auxiliary support, and is also convenient for repairing or iteratively updating the antenna in the limited space inside the mountain. The secondary radar station 300 uses inferior old radars for daily work, or discards radars as substitutes, so as to avoid the real main radar being accurately located in wartime, thereby greatly reducing the power consumption and operation of the main radar, extending its life, and enhancing its concealment. The secondary radar 301 can be reasonably arranged on the nearby hills or areas, and the main radar station 302 is generally used only in wartime to attack by surprise. , to increase the confusion, the frame structure 303 is set in the inner cavity of the mountain, and is fixed to the mountain as a whole by anchor rods. It is equipped with an anti-leakage layer and an anti-insect layer to prevent damage to the plant root system and collapse. The accompanying drawings are only for illustrative purposes, not for limitation. There are also a large number of construction operations such as foundations in the mountains. It is a universal component and can be constructed according to the terrain. The side beams 304 are used to imitate the top of the mountain.

It adopts a pulling base 212 and a guide base 211 to realize guide support, an annular guide ring A213 and an annular guide ring B214 to realize guide support, and a fixed support seat 215 is fixed by a top screw or a connecting piece. As a preferred embodiment, in order to realize better guidance, another annular groove is provided through the inner ring, and a guide support member B216 is placed to realize double guidance. The overall support is realized by the linkage of the articulated rod A217, the first articulated rod A218, the second articulated rod B219, the limit sleeve 220, the articulated seat A221, the articulated seat B222, the third articulated rod C223, the linkage articulated support rod B224, the articulated seat C225, the active connecting rod 226, the connecting articulated rod D227, and the connecting articulated seat D228, so as to facilitate better opening, and realize the support of the lifting support seat 207 and the antenna bottom support 229 by the central lifting rod 230. The present invention realizes the centralized collection of the connection and the opening when using it through the traction type connecting rod mechanism, which is convenient for transportation.

[0180] The present invention supports the whole through the frame assembly 100, and cleverly adjusts the connecting rod part 101 to cleverly design, and utilizes the smooth swing of the regular parallelogram in the mountain. When the radar component 2 is swung out, the anti-parallelogram is used to achieve the radar component 2 to reach the set position. Compared with a single regular parallelogram mechanism, it can achieve a smoother protrusion of the radar component 2 to avoid getting stuck. Compared with the anti-parallelogram mechanism, it can achieve the upward swing and contraction of the radar component 2 in the mountain, save space, and achieve a superposition effect. By coordinating and adjusting the swing part 102, polar coordinates are established to further increase the protrusion distance of the radar component 2.
