BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a receiving apparatus checking system for an electronic apparatus, and more particularly, to a receiving apparatus checking system for an electronic apparatus for checking the performance of a receiving apparatus of an electronic apparatus.

Generally, an electronic warfare apparatus receives an RF threat signal of a broadband, converts it into a baseband signal, fetches a video signal, and A / D converts the video signal to output a signal intensity, a frequency, a pulse repetition period (PRI) It is a device that can calculate the azimuth angle, measure the instantaneous frequency by using the signal converted into the baseband signal, or measure the signal arrival time, pulse width and pulse shape to identify the signal type such as missile / radar.

Here, the threat signal means an echo signal which is radiated by modulating a radar signal (baseband pulse waveform of a low frequency band, etc.) to a carrier frequency (modulation frequency) in a very high frequency band and is reflected back to a target (or a threat element) A modulated signal of a very high frequency band is converted into a signal of a middle band, a video signal corresponding to the radar signal after the demodulation process (a square wave type radar pulse waveform is distorted, which is commonly referred to as a video signal) .

It is very difficult to perform the performance test and the failure detection and inspection technology of the electronic warfare apparatus in the whole system to check whether any of the constituent devices in the electronic warfare apparatus affects the entire system due to the performance degradation. In addition, it is generally difficult to check the failure and performance of interworking between the components of electronic apparatus by merely checking the built-in test (BIT: Built-In Test) of the electronic warfare equipment, and it is possible to check whether or not the desired performance none.

Also, in order to test the performance of the developed electronic warfare apparatus, it is very costly to actually mount payloads such as aircraft / traps and threats (missiles or radar).

The receiver checking system of the electronic apparatus according to the present invention provides a technical feature that can easily check the receiver of the electronic apparatus even if it is difficult to grasp the information of the signal for inspection due to the interference of the external signal.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, Is provided to fully inform the user. Wherein like reference numerals refer to like elements throughout.

FIG. 1 is a diagram showing a threat signal generated by an inspection system of an electronic apparatus according to the prior art, and FIG. 2 is a diagram showing a result of analyzing various peripheral signals of a field maintenance unit by a spectrum analyzer.

Conventional electronic equipment has internally generated a signal source to confirm whether there is any abnormality in a signal receiving apparatus including an antenna and a signal analyzing apparatus. In other words, in existing electronic warfare equipments, it is judged whether there is an abnormality in the path with the internal signal source based on the already set path.

However, in order to check the signal coming in the antenna of the electronic warfare device, it can not be judged through the internal signal source, and the antenna should be checked with an external signal source. Therefore, as shown in FIG. 1, in an inspection system of most electronic apparatuses, an external signal such as a portable radiator or a multi-threat simulator, that is, a separate device for generating a threat signal, .

That is, in the case of conventional electronic warfare equipment, when a fault occurs internally during self-checking or when a power amplifier or the like is broken, a fault unit can be found through an internal signal source. On the other hand, If the attenuation is done, it is very difficult to find through the internal signal source. In addition, even when the radiation test is performed with an external signal source as described above, it is difficult to find a desired signal source due to interference of various communication signals.

As shown in FIG. 2, when analyzing the peripheral signal of the field maintenance unit received by the commercial DMB antenna with the spectrum analyzer, it is difficult to collect and analyze the signal source in a specific frequency region due to the interference of the illustrated signals. Therefore, if the interference signal can not be grasped, it is determined whether the signal source is generated inside the equipment, that is, an image or an harmonic signal generated from the internal signal source, Is collected normally but there is a problem with the algorithm, it is difficult to know whether the analysis module has an error.

Therefore, such a radiation test should be carried out in an anechoic chamber. However, in the case of field maintenance, there is no such expensive chamber of billions of billions, and indoor electromagnetic wave shielding curtains and wallpaper that cost hundreds of thousands of won to several hundreds of millions of won It is rare to have a test site consisting of mini-chambers used. As described above, it takes a lot of cost to maintain a separate facility to block external interference signals, and maintenance is difficult.

As described above, when an interference signal occurs due to environmental factors, it is best to find and remove the signal source, but it is very difficult to deter or remove the signal in the case of a mobile phone repeater or a communication signal.

3 is a diagram schematically showing a receiving apparatus checking system of an electronic apparatus according to an embodiment of the present invention.

Referring to FIG. 3, a receiving apparatus checking system 10 of an electronic apparatus according to an embodiment of the present invention is a receiving apparatus checking system 10 for checking a receiving apparatus 210 of an electronic apparatus 20, A peripheral signal measuring unit 110 for measuring signal information of signals; A threat signal generator 120 for emitting a threat signal based on the measured signal information; And a maintenance support unit (130) for comparing the signal type analyzed from the electronic apparatus (20) receiving the radiated threat signal and the threat signal radiated from the threat signal generation unit (120) The threat signal includes a continuous wave (CW).

As described above, in the case where an interference signal occurs due to environmental factors, it is very difficult to deter or remove the signal. Therefore, in order to solve this problem, the reception apparatus inspection system 10 of the electronic apparatus according to the embodiment of the present invention, Can radiate a continuous wave (CW) having a signal intensity larger than that of the surrounding interference signal to exclude the surrounding interference signal. That is, it is possible to easily remove external environmental factors by using a continuous wave (CW), rather than using an expensive anechoic chamber or an indoor mini-chamber using an electromagnetic wave shielding curtain and wallpaper.

In addition, the electronic apparatus 20 includes a receiving device 210 for receiving a threat signal emitted from the threat signal generating unit 120; An analyzer 220 for analyzing the threat signal received from the receiver 210 to identify a signal type of the threat signal; And a control unit 230 for controlling the receiving device 210 and the analyzing device 220.

Here, the electronic apparatus 20 is an independent apparatus that is subjected to a performance test and a failure or the like in the checking system 10 of the receiving apparatus 210 of the electronic apparatus 20 according to the embodiment of the present invention. And the detailed configuration and function of the electronic apparatus 20 will be obvious to those skilled in the art, so a detailed description thereof will be omitted.

The peripheral signal measuring unit 110 measures signal information of peripheral signals, that is, various interference signals received from the outside. Herein, the signal information may include signal intensity information, and the signal information of the peripheral environment signals measured by the peripheral signal measuring unit 110 is transmitted to the maintenance support unit 130.

The threat signal generator 120 emits a threat signal based on the signal information of the interference signals measured by the peripheral signal measurer 110. That is, the threat signal generator 120 emits a continuous wave (CW) for excluding the signal information based on the signal information of the surrounding environments transmitted to the maintenance support unit 130.

That is, when various interference signals (shown by dotted lines) are generated around the electronic apparatus 20 as shown in FIG. 4, the threat signal generator 120 generates a continuous wave (CW (S, solid line) of the threat signal (S) can be excluded. To this end, the signal strength of the continuous wave (CW) may have a signal strength greater than the maximum signal strength of the surrounding signals.

When a threat signal is emitted by the threat signal generator 120, the electronic device 20 receives the threat signal through the receiving device 210 and transmits the signal type of the received threat signal to the analyzer 220 Analyze. The receiving device 210 and the analyzing device 220 are controlled by the controller 230, respectively.

The signal type of the analyzed threat signal is transmitted from the controller 230 of the electronic apparatus 20 to the maintenance support unit 130. The maintenance support unit 130 analyzes the signal type of the threat signal from the electronic warfare apparatus 20, And compares the received signal type with the threat signal radiated from the threat signal generating unit 120 to determine whether the signal is abnormal. Here, the maintenance support unit 130 may include a waveform analyzer or the like for analyzing the signal on the time axis to compare the signal type of the continuous wave (CW).

Preferably, the signal type of the threat signal identified by the analysis device 220 of the electronic apparatus 20 further includes azimuth information, and the maintenance support unit 130 may receive the azimuth information set by the threat signal generator 120, With the azimuth angle identified by the analyzer 220, to determine whether the abnormality is abnormal.

For example, when the threat signal generator 120 emits radiation with the azimuth angle set to 30 degrees, if the value received by the electronic warfare apparatus 20 is 25 degrees, it will have an error value of 5 degrees. It can be determined that an error has occurred in the internal device or module of the electronic apparatus 20 due to the error value.

In addition, the receiving device 210 of the electronic apparatus 20 may include a receiving antenna (not shown) and a front end receiver (not shown) for modulating a signal received from the receiving antenna.

As described above, the electronic apparatus 20 internally generates a signal source to check whether there is any abnormality in the receiving apparatus 210 and the analyzing apparatus 220 including the antenna. However, when a signal is received from the antenna of the electronic apparatus 20 It is impossible to find out whether the incoming part, that is, whether there is a short circuit between the antenna and the front end receiver or whether the signal is attenuated, through the internal signal.

Therefore, according to the reception apparatus checking system 10 of the electronic apparatus according to the embodiment of the present invention, in a multi-high density environment of surrounding environment signals, external verification signals, that is, threat signals , It is possible to generate a remarkable effect that the check between the antenna 20 and the front-end receiver for each band can be solved at an optimum cost in a short time.

In addition, the electronic apparatus 20 may include an unmanned automated apparatus. That is, the reception apparatus checking system 10 of the electronic apparatus according to the embodiment of the present invention measures the signal information of the surrounding environment signals, radiates a continuous wave having a signal intensity larger than the maximum signal intensity of the surrounding signals, It is possible to easily check whether or not the receiving apparatus 210 is abnormal without user intervention by comparing and analyzing the result received from the apparatus 210 and analyzed by the analyzing apparatus 220. [

While the preferred embodiments of the present invention have been described and illustrated above using specific terms, such terms are used only for the purpose of clarifying the invention, and the embodiments of the present invention and the described terminology are intended to be illustrative, It will be obvious that various changes and modifications can be made without departing from the spirit and scope of the invention.
