4 is a block diagram of another embodiment of an antenna station for receiving a short pulse (about 20 msec) according to the present invention.

The three antenna stations 101 to 103 may be basically configured as follows.

As shown in the figure, the antenna station according to the present invention includes six reception antennas 401 for receiving a radio signal transmitted from the transmitter 109 and six reception antennas through the six reception antennas 401.

5 is a flowchart illustrating an embodiment of a method for detecting a radio signal origination position according to the present invention.

First, when the radio signal transmitted from the transmitter 109 is received at three antenna stations 101 to 103 each consisting of six antennas (501), the radio signal received at each antenna of each antenna station 101 to 103 is received. The strength information of each is detected (502), and the code information of the caller is detected from the strongest wireless signal among the six wireless signals received by the six antennas for each antenna station (503).

The three antenna stations 101 through 103 monitor the strength information of the radio signals and the code information of the caller, respectively, and output the state of the antenna stations 101 through 103 to the operator (504).

The difference between the six radio signal strengths included in each antenna station 101 to 103 among the strength information 18 of the radio signals detected at each of the three antenna stations 101 to 103 is determined. After obtaining the reception angles of the radio signals received at each antenna station 101 to 103, respectively, the radio signal transmission position is detected by the correlation between the distance between the three antenna stations 101 to 103 and the reception angle. (506).

6 is a diagram illustrating a center angle and a gain curve of an antenna for explaining a process of obtaining a reception angle of a radio signal.

First, a method of correcting the reception angle of an antenna is as follows.

As shown in the figure, a1 to a6 are the center angles to which the antenna is directed, and V1 to V6 are gain curves of the antennas from antennas 1 to 6, and the reception direction of the radio signal is between a1 and a2. In this case, the six antenna measurements show the highest radio signal strength at antenna 1 or 2, if the 1 side is larger, the reception angle is biased more toward a1.

On the other hand, the absolute value of the radio signal strength varies according to the distance and the situation of the source. However, since the difference in the strength of the radio signal of each neighboring antenna is independent of the distance of the source, the reception angle is determined using the difference in the strength of the radio signal. You can get it. However, since the characteristics of the antenna are different, the curve of FIG. 6 can be obtained by correcting the following equation (1) through a plurality of measurements.

That is, when the reception angles T1 and T2 are known between arbitrary antennas n-1 and n in Equation 1, the difference in the strength of the radio signal measured Is applied to Equation 1, from the quadratic equation When the curve is obtained, the angle of the radio signal received at any angle between antennas n-1 and n can be obtained by calculation. Likewise The value of can be reduced by using the average value through several experiments.

Next, the process of obtaining the reception angle of the radio signal is as follows.

As described above, when the reception angle of the antenna can be estimated by using the difference in the strengths of the radio signals of neighboring antennas, the antenna with the highest radio signal strength measured from six antenna measurements is V _n . In this case, the strength of the radio signal is selected from among the strengths of the radio signals V _n-1 and V _{n + 1} of neighboring antennas. If V _n-1 is larger, the reception angles are a _n-1 and a and between _n, V _n-1 -V _n finally received from the angle Can be obtained.

7 is a flowchart illustrating another embodiment of a method for detecting a location of origination of a radio signal according to the present invention.

First, the transmitter 109 is transmitted from each location by dividing the service area by 50 m intervals in advance, and the strength of the radio signal from each antenna station 101 to 103 is stored in the memory for each transmission point. 18 total (6 antennas The strength of the radio signal of each antenna station is stored, and the neural network learns the correlation between the measured intensity data of the radio signal and its transmission angle position (701) at the actual position of the transmitter (109). When the transmitter transmits by using the strength of the radio signal of each antenna to determine the output position.

Thereafter, when the radio signal transmitted from the transmitter 109 is received at three antenna stations 101 to 103 each consisting of six antennas (702), the radio signal received at each antenna of each antenna station 101 to 103 is received. The strength information of each is detected (703), and the code information of the caller is detected from the strongest radio signal among the six radio signals received by the six antennas for each antenna station (704).

In operation 705, the three antenna stations 101 to 103 monitor the strength information of the radio signals and the code information of the sender, respectively, and output the state of the antenna stations 101 to 103 to the operator.

In operation 706, the neural network detects a radio signal transmission position according to the learning result using the strength information 18 of the radio signals detected by the three antenna stations 101 to 103, respectively.

Then, by calling the map of the location according to the detected location information of the wireless signal source, and displays the location of the wireless signal on the map, and retrieves the caller information by searching the database stored the caller's personal history with the code information of the caller (707).

As described above, the method using the neural network is a state-of-the-art method that can be usefully used in a region where it is difficult to use a method of detecting a transmission position by obtaining a reception angle of a radio signal due to a complicated radio wave environment. The neural network is similar to the configuration and operation method of a general neural network.

8 is a flowchart illustrating a method for receiving a short pulse in an antenna station according to another embodiment of the present invention.

First, when the radio signals transmitted from the transmitter 109 are respectively received by the six reception antennas 401 (801), the six radio signals are demodulated by the six reception units 402, respectively. Each intensity is detected (802).

Thereafter, one of the six receivers 402 is selected according to the code selection control signal (3 bits) (803) to convert the wireless signal strength information and the caller code information in the analog form of the selected receiver 402 into a digital form. After that, the strength information of the radio signal is detected (805).

Subsequently, it is determined whether all receivers 402 are sequentially selected (806) or generates a code selection control signal of the next order (807) and repeats from the receiver selection process (803), and if all are selected, the strongest After selecting the radio signal and detecting the sender code information carried on the radio signal (808), the detected sender code information and the strength information of the six radio signals are transmitted (809).
