Problems solved by technology
[0005] Although this technical solution can realize the array has the functions of beam two-dimensional phase scanning and polarization online real-time reconstruction, but this solution cannot make the phased array radar antenna foldable and put it into a backpack, so that it is convenient for soldiers to carry it while marching in the tropical rainforest. And survey the surrounding targets; it is also impossible to drill holes on the tree branches and clamp the branches through the drilling rig, and it cannot be fixed on the trunk by barbs, and it cannot still work normally in a strong wind environment, so there are still many defects in this technical solution

Embodiment Construction
[0026] use Figure 1 to Figure 7 A kind of portable phased array radar antenna of the present invention is described as follows, the front, back, left, and right directions involved in the present invention are all represented by image 3 as the benchmark.
[0027] Such as Figure 1 to Figure 7 As shown, a portable phased array radar antenna according to the present invention includes a T / R assembly 1, a hydraulic cylinder 2, a rotating plate 3, a support plate 4, a drilling machine 5 and a grapple 6; the T / R assembly 1 The upper left lower end of the upper part is hinged with the lower left upper end of the T / R assembly 1; the rotating plate 3 is installed above the support plate 4; the drilling machine 5 is installed below the support plate 4; the grapple 6 is installed on the support On the edge of the lower side of the plate 4, the number of grapples 6 is three to four, and the grapples 6 are evenly distributed on the edge of the lower side of the support plate 4, and th...

The invention belongs to the technical field of phased array radar antennas, and particularly relates to a portable phased array radar antenna. The antenna comprises a T / R assembly, a hydraulic cylinder, a rotating plate, a supporting plate, a drilling machine and a grabbing hook. A thrust bearing is arranged between the rotating plate and the supporting plate, and the drilling machine is connected to the supporting plate through a folding and unfolding mechanism; a double-head motor is arranged in the supporting plate; a first groove is formed in the side face of a first plunger rod, and a first sliding block and a second sliding block are arranged in the first groove. A pressure oil bag is arranged below the second sliding block. A cutting edge is arranged on the upper side face of the first rod. A first through hole is formed in the first plunger rod, and a two-way overflow valve is arranged in the middle of the first through hole. According to the invention, the phased array radarantenna can be folded and put into a knapsack, so that a soldier can conveniently carry the phased array radar antenna in a tropical rainforest to march and investigate surrounding targets; holes aredrilled in a crotch through the drilling machine, the crotch is clamped, the drilling machine is fixed to the trunk through the barb, and therefore, the phased array radar antenna can still work normally in the strong wind environment.
Description
technical field [0001] The invention belongs to the technical field of phased array radar antennas, in particular to a portable phased array radar antenna. Background technique [0002] Phased array radar is a phase-controlled electronically scanned array radar. A large number of individually controlled small antenna units are arranged into an antenna array. Each antenna unit is controlled by an independent phase-shift switch. Synthesize beams of different phases. The electromagnetic waves emitted by each antenna unit of the phased array synthesize a near-straight radar main lobe based on the principle of interference, while the side lobes are caused by the inhomogeneity of each antenna unit. [0003] The antenna array of a phased array radar consists of many radiation and receiving units (called array elements). The number of units is related to the performance of the radar, and can range from hundreds to tens of thousands. These units are regularly arranged on a plane to...
