Description

Technical Field

[0001] The invention relates to the technical field of weapons and ammunition, and in particular to a mother-and-child type intelligent armor-piercing projectile based on a W-band millimeter wave radar. Background Art

[0002] In modern warfare, tanks and armored vehicles are often equipped with a layer of explosive reactive armor (or active protection system) on their protective front or side to reduce the threat of anti-tank weapons. When the tank is attacked, the equipment can interfere with the attack on the tank by means of explosive explosion, effectively weakening the destructive effect of these anti-tank weapons and achieving the purpose of preserving the tank and armored vehicles. At present, reactive armor has become the mainstream of additional armor for tanks and armored vehicles in the world. When ordinary armor-piercing projectiles penetrate the tank armor equipped with reactive armor, they will first hit the reactive armor, and the outer steel plate of the reactive armor will be penetrated, and the insensitive explosives inside will explode, and the explosion of the explosives will blow up the outer steel plate. The metal fragments and detonation airflow generated in this process will interfere with the flight trajectory of the rod-type armor-piercing projectile and consume the kinetic energy of the armor-piercing projectile, eventually causing the armor-piercing projectile to deflect or even break into several sections, deviating from the predetermined flight state, so that it cannot effectively damage the main protective armor, thereby reducing the penetration ability of the armor-piercing projectile to the target. The ability of reactive armor to resist the penetration of armor-piercing projectiles can reduce the armor-piercing power by 30% to 50%.

[0003] Ordinary armor-piercing shells mostly use pointed structures, which are prone to ricocheting when attacking armor plates with large inclination angles, resulting in low armor-piercing effect; while blunt-nosed armor-piercing shells can improve the ricochet problem, but due to the large equivalent windward surface of the bullet, the resistance is greater, so the speed drops significantly and the effective range is insufficient. The diversity of armored targets has prompted the emergence of more new types of kinetic damage ammunition, and they are developing in the direction of multifunctional and efficient damage. In order to better cope with changes in the battlefield situation, it is necessary to study a more reliable armor-piercing shell that can still effectively penetrate the tank armor after destroying the tank armor, so as to achieve the purpose of destroying the tank. Summary of the invention

[0009] Furthermore, the Doppler frequency of the W-band millimeter-wave radar device is 1 MHz-10 MHz.

The antenna uses circular polarization, and the transmitting and receiving antennas use array antennas with separate transmit and receive locations and opposite polarization to ensure transmit and receive isolation between antennas.

[0011] Furthermore, the signal processing of the W-band millimeter wave radar device includes analog-to-digital conversion A / D, 1D fast Fourier transform (1D-FFT), filtering, two-dimensional FFT transform (2D-FFT), modulus finding, non-coherent accumulation, ranging and detonation distance judgment, and detonation command signal output.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention installs a W-band micro millimeter-wave radar device at the head of an armor-piercing projectile.

This attack mechanism can avoid the interference of the reactive armor and achieve the purpose of destroying the main armor. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 1. Overall parameter design of the mother-and-child intelligent armor-piercing projectile

[0030] 1. Design parameter calculation

[0031] The bullet firing chamber at the head of the main penetrator is relatively short, and there is no secondary action process in the general sense of internal ballistics. The internal ballistic performance is not easy to stabilize. In order to reasonably select the design parameters, some calculations must be made to obtain a regular relationship. Through calculations, it is found that: under the premise that the propellant is not completely burned, the increase in bullet weight is beneficial to increasing the initial velocity; under the current projectile structure, when the initial velocity of the projectile reaches about 200m / s, the projectile speed does not lose when breaking the shell, etc. The analysis and calculation are as follows.

[0032] (a) The thickness of the locking ring and the speed of the bullet flying away from the mother bomb

[0033] The conclusion is: when the thickness of the locking ring changes from 1mm to 5mm, the speed of the bullet flying away from the mother bullet is almost unchanged, which shows that the thickness of the locking ring has little effect on the speed of the bullet flying away from the mother bullet. In engineering, the role of the locking ring can be achieved by shearing the bullet tip thread.

[0034] (b) The length (mass) of the bullet and the speed at which the bullet leaves the mother projectile

[0035] In the case of a certain amount of charge, if the gunpowder is not fully burned, the length of the bullet (the caliber remains unchanged, the length is the mass, the same meaning below) and the speed of the bullet flying away from the mother bullet will increase with the increase of the length of the bullet, that is, the increase of the mass of the bullet, and the speed of the bullet flying away from the mother bullet will increase. The increase in the mass of the bullet will also increase the speed of its flying away from the mother bullet.

[0036] (c) Relationship between bullet length and maximum pressure Pm in the firing hole

[0037] The relationship between the length of the bullet and the maximum pressure Pm in the firing hole under different charges: As the length of the bullet increases, that is, the mass of the bullet increases, the maximum pressure in the firing hole of the mother bullet head will also increase, and the magnitude of this increase will increase with the increase in charge.

[0038] (d) The relationship between the length of the bullet and the time t required to fire the bullet

[0039] The relationship between the length of the bullet and the time t required to fire the bullet under different charges: For a bullet of a certain size, when the charge increases, the time required to fire the bullet will be shortened; when the length of the bullet increases, that is, the mass of the bullet increases, the time required to fire the bullet has almost no change, which shows that the time required to fire the bullet is not very sensitive to the change in the mass of the bullet. Generally, the time it takes for a bullet to leave the barrel is about 0.8ms.

[0040] 2. Intelligent sub-type armor-piercing warhead design

[0041] (a) Basic calculation

[0042] In order for the mother-and-child smart armor-piercing projectile to achieve the expected tactical purpose, the speed of the bullet flying away from the mother projectile must reach about 250m / s. To achieve this requirement, the length of the bullet can be 14mm and the charge of the propellant can be 1.4g. In this way, after calculation, the speed V of the bullet flying away from the mother projectile can be obtained. re =265m / s, which obviously meets the design requirements.

[0043] Through calculation, it is found that the gunpowder is not completely burned in the firing hole, and the time taken for the bullet to fly away from the mother bullet is 0.824ms. At the moment when the bullet flies away from the mother bullet, the burning rate of the gunpowder is ψ=0.27. The bullet has a maximum speed in the process of firing the mother bullet, and the magnitude of this maximum speed is 269.73m / s. The moment when this maximum speed occurs is the moment when the bullet contacts the head screw of the mother bullet. After that, because the bullet has to cut off the thread of the head screw, it is subject to the resistance of the head screw, so the speed of the bullet will decrease. The maximum pressure in the firing hole during the firing process of the bullet is nearly 300Mpa. After reaching the maximum pressure, the pressure in the firing hole begins to decrease. However, when the bullet contacts the head screw of the mother bullet, the amplitude of the pressure drop in the firing hole decreases. This is due to the resistance applied to the bullet by the head screw.

[0044] (b) Verification of the strength of the warhead of the mother missile

[0045] During the firing process of the bullet, very high pressure will be generated in the firing hole of the mother bullet. In order to avoid the danger of explosion caused by excessive pressure in the firing hole, it is necessary to perform an elastoplastic analysis on the warhead of the mother bullet.

[0046] In engineering, we generally divide cylinders into thick-walled cylinders and thin-walled cylinders. When the ratio of the outer diameter to the inner diameter is less than 1.1-1.2, it can be analyzed as a thin-walled cylinder, and when it is greater than 1.2, it can be analyzed as a thick-walled cylinder. For the specific problem we analyzed, the ratio of the diameter of the bullet head to the diameter of the launch hole is 30 / 7, so it is obviously necessary to treat it as a thick-walled cylinder.

[0047] When conducting elastic-plastic analysis on the warhead of the mother missile, it is assumed that the material is ideally elastic-plastic and that the material is incompressible in both the elastic and plastic zones. Only in this way can a complete solution to the problem be obtained.

[0048] The result of processing as a thick-walled tube is that the current structure meets the emission strength requirements.

[0049] (c) Hood and exterior design

[0050] The main factors considered in the design are the shape (external ballistics), shell breaking force (consistency), etc. The current hood shape is no longer the traditional hood shape, it is just a small plug, and the actual shape is reflected by the outside of the projectile.

[0051] (d) Head structure design

[0052] When designing the head structure, the main considerations are the relationship between the inner and outer diameters of the firing cavity and the cavity strength, the relationship between the firing device (amount of charge) and the inner cavity length and bullet mass, as well as the overall layout.

[0053] 2. Design of W-band micro millimeter-wave radar device

[0054] The W-band micro millimeter wave radar device consists of an RF front end, analog-to-digital conversion, signal processing, frequency modulated continuous wave signal source, and MCU. The RF front end transmitting part consists of a 4-frequency multiplier, a driver amplifier, and a final power amplifier, and the receiving part consists of a low noise amplifier, a down converter, and an intermediate frequency amplifier. The RF front end is manufactured based on the domestic 100nm pHEMT millimeter wave integrated circuit process. The FMCW signal source, signal processing, and MCU design use optimized integration of transmission, reception, and mixing functions to achieve 1T1R monolithic integration. This achieves high integration and low power consumption of the W-band micro millimeter wave radar device, meeting the requirements of small size, reduced manufacturing production costs, light weight, high performance, and high reliability.

[0055] 1. Millimeter wave active 4-multiplier low power consumption technology

[0056] The design of the 4-frequency multiplier is implemented using the classic active frequency multiplier circuit structure. Since the input frequency of the frequency multiplier is 22GHz, the output frequency reaches 88GHz after 4-frequency multiplication. The output frequency is too high to be achieved by a single-stage active frequency multiplier circuit structure. Therefore, a one-stage active frequency multiplier plus a four-stage amplifier design is required, which is implemented using the 4th harmonic matching and the remaining harmonic suppression technology.

[0057] 2. Millimeter-wave active mixer low power consumption technology

[0058] The design of the mixer is realized by using the classic active circuit structure design. The millimeter wave mixer operates at a high frequency band, and it is difficult to achieve high image suppression and low frequency conversion loss. The structure of the mixer plus a low-pass filter is used.

[0059] 3. Millimeter wave low noise and low power consumption technology

[0060] The design of the low noise amplifier is realized by using the classic active low noise circuit structure. The operating frequency of the low noise amplifier is 94GHz. It is difficult to achieve low noise and gain above 25dB under this frequency condition. Too few amplifier stages will lead to insufficient gain, and too many stages will lead to increased noise and other problems. Therefore, considering the comprehensive consideration of the low noise amplifier sampling four-stage amplification, the noise matching technology is used for noise optimization to achieve low noise and high gain.

[0061] 4. Power amplifier high efficiency and low power consumption technology

[0062] The design of the power amplifier is realized by using a typical common-emitter amplifier circuit structure cascade design. The millimeter-wave power amplifier operates at 94GHz. It is very difficult to achieve high gain, high power, high gain, and high efficiency under high frequency conditions. The design adopts four-stage signal amplification. The last stage uses multi-tube parallel connection and power synthesis to increase the output power. Loadpull is used to find the impedance area where the equal power circle and the equal efficiency circle overlap to achieve impedance matching, and achieve the best output matching of the efficiency and power of the power amplifier.

[0063] 5. High-frequency millimeter-wave AIP chip packaging technology

[0064] The present invention adopts AIP packaging technology antenna packaging technology (Antenna on / in Package, AoP / AiP), which can be designed to integrate the millimeter wave radar antenna directly into the packaging substrate, thereby reducing the size of the sensor and the complexity of the sensor design packaging. The antenna adopts circular polarization, and the transmitting and receiving antennas adopt array antennas with separate transceivers and reverse polarization to ensure the isolation of transceivers between antennas. The radome is made of high-strength and high-temperature resistant composite materials, which has low loss characteristics and can effectively improve the wave transmittance.

[0065] 6. Radar indicator design

[0066] (1) Radar waveform selection

[0067] Due to the coupling problem of distance and speed of continuous wave radar, the Doppler frequency of the target echo will be coupled to the receiving frequency. The Doppler frequency of this radar chip is as high as 1MHz. In order to reduce the impact of the Doppler frequency, the repetition frequency needs to be increased as much as possible during product design. However, the bandwidth of the radar baseband cannot be too high, which affects the radar design.

[0068] The radar carrier runs at a speed of up to 1700m / s, flying 1.7m per millisecond. The carrier moves fast, so the stay time in a distance resolution unit is very short, resulting in a large effective bandwidth for signal processing and poor receiver sensitivity. Therefore, the design of the transmission waveform index needs to be paid attention to.

[0069] In the design, the radar transmission waveform is a combination of sawtooth linear frequency modulation continuous wave and point frequency sine wave. Figure 4 shown.

[0070] The radar first transmits a group of multiple sawtooth waves with a sawtooth wave period of T1, and then sends a single frequency to measure the carrier speed, and repeats this transmission.

[0071] The W-band micro millimeter wave radar device of the present invention occupies the positions of the original armor-piercing projectile wind cap and armor-piercing block, the sub-mother-and-child armor-piercing projectile projectile and the head plug block meet the requirements of the external ballistics, and the projectile itself has the ability of positive and oblique penetration. Therefore, the sub-mother-and-child intelligent armor-piercing projectile anti-reactive armor does not lose the penetration power at the cost of the W-band micro millimeter wave radar device. The ignition command is issued under the preset conditions, and a small bullet is fired to detonate the reactive armor, and the subsequent armor-piercing projectile body penetrates the armor. Avoiding the interference of the reactive armor, the purpose of destroying the main armor is achieved.

[0072] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
