Embodiment 1

[0037] The hand-held pressing equipment that the preferred embodiment of the present invention provides, such as figure 2 As shown; the total length of the hand-held pressing device is 45CM, and the total width is 10.7 cm; the length of the handle 2 is 12 cm, which is to ensure the convenience of operating the power switch button 3 and the pressing switch button 4 with one hand;

[0038] When working: The core host of the hand-held suppression equipment is an integrated design. Through the power switch and suppression switch, the interference source module automatically controls each suppression source and power amplifier module. For blocking interference of remote control and image transmission signals, 1100MHz~1300MHz, 1558MHz~1592MHz are mainly used for blocking interference of GPS and BDS satellite positioning signals, effectively blocking the UAV flight control system and signal transmission system, so that it can The loss of flight control commands and satellite positio...

Embodiment 2

[0040] Hand-held pressing equipment provided by the invention, such as image 3 Shown; Adopt the pistol structure, the operator holds the handle 6 of the gun body, and the knuckles pass through the ring hole to touch the pressing switch button 7, which is very convenient for one-handed operation. The power button of this structure is set at any operable position; because the power button is a one-time switch when in use; and for different types of pressing equipment, the nameplate is placed in the nameplate placement port provided on the outer wall of the barrel.

[0041] When working: if Figure 4 As shown, considering the frequency range of the signal source is 1GHz to 20GHz, it is difficult to use a phase-locked loop to output directly, so a loop is used to output 10GHz to 20GHz, and the frequency is switched by a switch. When outputting 10G to 20G, The switch strobes the direct channel to output directly. When outputting 3-10G, the switch strobes the frequency divider. Th...

Embodiment 3

[0043] On the basis of Example 2, do phase noise analysis; according to the actual test, when the phase detection frequency of HMC704 is 100MHz, the noise floor in the fractional frequency division mode of the main ring=-216+10log10000000=-136dBc / Hz, and the highest output frequency is 15GHz , the phase noise deterioration multiple N=15000 / 100=150, 20log150=43, -136+43=-93dBc / Hz@10KHz. According to the VCO manual, its phase noise is -70dBc / Hz@10KHz, and because the loop bandwidth has the characteristics of a high-pass filter on the VCO phase noise, in order to reduce the influence of the VCO phase noise, the loop bandwidth should be larger, preliminary consideration is 300KHz, and the noise introduced by the VCO at this time is -70-20log30=-98dBc / Hz@10KHz. In addition, it can be inferred from the reference signal that the final result of the superposition of the two main phase noises of the PLL can reach - 85dBc / Hz@10KHz.

Abstract

The invention discloses a hand-held suppressing device, which includes a housing provided with a power switch and a suppressing switch, an interference source module, a radio frequency module connected to the suppressing switch, and a power supply module connected to the power switch are arranged inside the housing; the interference source module Including two noise generation units, the second frequency synthesizer receives the Gaussian white noise source signal and the chaotic interference noise source signal and synthesizes it into a suppression interference signal; sends the suppression interference signal to the voltage-controlled oscillator, and the voltage-controlled oscillator receives the suppression interference signal and It is amplified by the first power amplifier, sent to the third filter amplifier for filtering processing, and the suppressed interference signal after filtering is input into the second power amplifier, and the amplified suppressed interference signal is input into the logarithmic interference antenna for high-gain amplification and radiation into the air, effectively To control the "Black Fly" UAV; the housing includes a pressing body, the pressing body is connected to a handle, and the connection is provided with a power switch button and a pressing switch button.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle suppression, and relates to hand-held suppression equipment. Background technique [0002] In recent years, the UAV market has grown rapidly. With the large-scale [0003] R&D and production have made civil (commercial) UAVs extremely cost-effective, and their popularity is getting higher and higher. UAV systems have been widely used in various industries, greatly enriching the work of various industries and people's daily life. [0004] However, the domestic supervision of drones, especially "black flying" and "random flying" drones is still in a blank state. [0005] The proportion of black and random flying of small, micro, and nano drones flying in the air is about 90%, which is a great threat to air surveillance. [0006] Air management and air safety have caused great hidden dangers, seriously affecting the take-off and landing of aircraft, disrupting the safety of public activities,...
