DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the implementation methods of the present invention or the technical solutions of the prior art, the present invention is described in more detail below in conjunction with the accompanying drawings. Obviously, the following drawings are only some implementation methods of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0029] like Figure 1 As shown, the present invention provides a light towed suppression rocket jammer, comprising a rocket jammer body 1, a turbine 2, a combustion chamber 3, an amplifier chamber 7 and a warhead 11, the turbine 2 is disposed at the tail of the rocket jammer body 1, the combustion chamber 3 and the amplifier chamber 7 are located in the rocket jammer body 1, the warhead 11 is located at the front end of the rocket jammer body 1, and the warhead 11 is rigidly connected to the rocket jammer body 1.

[0030] like Figure 3As shown, the turbine 2 includes a hollow shaft 201 and inclined tooth surfaces 202 evenly distributed along the outer wall of the shaft. The turbine 2 is connected to the rocket jammer body 1 through the hollow shaft 201. The design of the hollow shaft 201 can be connected to the combustion chamber 3 at the bottom of the rocket jammer body 1 on the one hand, and on the other hand, it also reduces the weight of the turbine structure. The inclined tooth surface 202 has a certain inclination angle. When the gas in the combustion chamber 3 is ejected to the inclined surface, the turbine 2 rotates and drives the missile body to rotate, so as to achieve the function of balancing the jammer body. Figure 1 As shown, the turbine 2 is located in the turbine chamber, and there are six air flow holes at the tail of the turbine chamber. The axis of the air flow holes is at a certain angle to the axis of the rocket jammer body. After passing through the turbine 2, the gas is basically evenly ejected from the six air flow holes at a certain angle at the tail. The ejected gas not only gives the rocket jammer power, but also gives the rocket jammer a radial speed, causing the rocket jammer to spin to improve the stability of the rocket jammer during flight.

[0031] The combustion chamber 3 is located in the middle and lower part of the rocket jammer body 1, at the front end of the turbine 2. The combustion chamber 3 stores propellant 4, and the bottom of the combustion chamber 3 is provided with an airflow hole 5. The propellant 4 in the combustion chamber 3 provides power for the jammer, and is used to achieve the purpose of launching the jammer, and has no actual lethality. The propellant 4 burns in the combustion chamber 3 and ejects gas from the airflow hole 5 to achieve the launch, and drives the turbine 2 to rotate and stabilize the jammer body.

[0032] The power amplifier chamber 7 is located in the middle and upper part of the rocket jammer body 1, at the front end of the combustion chamber 3, and a heat dissipation grille 6 is provided between the power amplifier chamber 7 and the combustion chamber 3, and the heat dissipation grille 6 can dissipate the heat propagated upward from the combustion chamber 3; in a specific implementation of the present invention, the heat dissipation grille 6 adopts a cylindrical grille structure, and the cylindrical grille structure fits the inner wall of the rocket jammer body 1. The heat dissipation grille 6 can effectively ventilate and dissipate heat, ensuring that the power amplifier module works in a suitable environment.

[0033] The power amplifier room 7 contains a signal jammer 8. In this embodiment, the signal jammer 8 includes five power amplifier module boxes 81, power amplifier modules placed in the power amplifier module boxes 81, a battery pack 9 for powering the power amplifier modules, and a power amplifier module box cover 83 for sealing the power amplifier module boxes 81. Each power amplifier module box 81 also contains a heat sink 82, which is used to ensure that the power amplifier module will not overheat during circuit operation. The power amplifier modules in the power amplifier module boxes 81 are connected to the guide head 10 via SMA wires. The battery pack 9 is composed of a plurality of batteries 105. The battery pack 9 not only supplies power to the power amplifier modules, but also supplies power to the guide head 10.

[0034] like Figure 4As shown, the power amplifier module box 81 is provided with grooves and threaded holes 811 of different sizes, and through holes are provided at both ends. It is embedded in the upper and middle part of the jammer bomb by screw connection. The power amplifier module and its corresponding circuit structure are fixed in the corresponding grooves by countersunk screws. The power amplifier module box cover 83 is connected to the main part of the power amplifier module box 81 by threads, and is also fixed to the power amplifier module box 81 by countersunk screws, and cooperates with the power amplifier module.

[0035] Take the rocket interception system based on the EL / M-2084 multi-task active phased array radar as an example. The operating band of the EL / M-2084 multi-task active phased array radar is the L band, and its frequency range is 1GHz to 2GHz. Therefore, in the power amplifier module, this embodiment uses a V1116-10 voltage-controlled oscillator to generate 1GHz to 2GHz noise waves, and connects to the first-stage signal amplification circuit. The first stage uses a YG602020 broadband RF gain amplifier with a gain of 20dB, which amplifies the original signal to 100 times the original. The amplified signal is input into the second-stage signal amplification circuit. The second stage uses MW6S004NT1, which continues to amplify the signal by about 64 times on the original basis, so that the noise reaches sufficient output power to affect the positioning and tracking capability of the EL / M-2084 multi-task active phased array radar to the rocket. Because the frequency band of the noise wave generated by the power amplifier module covers all the frequency bands of the EL / M-2084 multi-task active phased array radar, this rocket jammer has a suppressive effect on the EL / M-2084 multi-task active phased array radar. Finally, the signal after two stages of amplification is connected to the antenna unit through BLP15M9S70 (a 70W general-purpose LDMOS RF power transistor) to realize the broadcast and output functions to affect the work of the EL / M-2084 multi-task active phased array radar. The detailed design of the circuit is omitted here. Those skilled in the art can adjust the circuit structure according to the actual situation. The circuit structure is well known in the art and will not be repeated.

[0036] like Figure 2 As shown, the warhead 11 is placed at the front end of the rocket jammer body 1 to reduce air resistance; the seeker 10 is built into the warhead 11 .

[0037] like Figure 3As shown, the seeker 10 is composed of a plurality of antenna units 101, and the antenna units 101 are circumferentially arranged on an antenna support plate 102 through an L-shaped connector 103 to form a circular array. In this embodiment, the antenna unit 101 is composed of a convex antenna plate 1011 and a pair of circular disks 1012, and the protruding end of the top of the convex antenna plate 1011 is vertically fixed on the antenna support plate 102 through the L-shaped connector 103, the bottom of the convex antenna plate 1011 is located outside the antenna support plate 102, and the pair of circular disks 1012 are installed in parallel at the bottom of the convex antenna plate 1011, and the pair of circular disks 1012 are symmetrical about the convex antenna plate 1011 and parallel to the antenna support plate 102. The antenna bracket plate 102 is provided with a threading hole 1021, and the SMA wire connected to the antenna unit 101 passes through the threading hole 1021 and is connected to the power amplifier module in the power amplifier module box 81. The noise wave generated by the power amplifier module is transmitted to the seeker 10 through the SMA wire, and the output wave is amplified and emitted by the antenna unit 101 to achieve the purpose of interfering with the radar signal.

[0038] In a specific implementation of the present invention, the shell size of the rocket jammer body 1 can be designed according to actual conditions, and the shell material is made of titanium alloy, beryllium alloy and other materials, which has the advantages of high strength, corrosion resistance, light weight and low cost.

[0039] In a specific implementation of the present invention, the jammer can be used in combination with an existing rocket and its launch device and launched together with the existing rocket. The present invention has no actual killing effect and can interfere with radar signals in a rocket group, making it impossible for the radar to accurately locate the rocket group.

[0040] The above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and many variations are possible. All variations that can be directly derived or associated with the contents disclosed by a person skilled in the art should be considered as the protection scope of the present invention.
