DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 1-pulse receiving radio wave specification analyzer for receiving a radio wave from a radio wave source and simultaneously measuring the direction of the radio wave source and the specifications of the radio wave.

[0002]

2. Description of the Related Art FIG. 4 is a block diagram showing a conventional direction finding and radio wave specification analyzer. In FIG. 4, reference numeral 1 denotes a radio wave specification analyzer for analyzing radio wave data of a radio wave source; A receiving antenna for receiving a radio wave transmitted from the source, a direction finding device for measuring the azimuth of the radio source, and the above-mentioned radio wave specification analyzer 1 and the direction finding device 3 are connected to a receiving antenna 2, respectively.

Next, the operation will be described. The radio wave specification analyzer 1 analyzes the radio wave frequency, radio wave intensity, radio wave pulse width, and the like of the radio wave of the radio wave source received by the reception antenna 2, and the direction finding device 3 uses the reception antenna 2 The radio wave of the received radio wave source is received, and the direction of the radio wave source is measured using the frequency information analyzed by the radio wave specification analyzer 1.

[0004]

Since the conventional direction finding and radio wave specification analyzer are constructed as described above, in order to obtain the azimuth of the radio wave source, the frequency of the radio wave source must be known beforehand. However, it is necessary to receive at least a plurality of pulsed radio waves for direction finding and radio wave specification analysis, and when radio waves of different frequencies arrive at the same time, there are problems such as determining different directions. was there.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to know the azimuth of a radio wave source even if the frequency is not known, and to simultaneously receive different radio waves of different frequencies. Can also determine the true bearing
It is an object of the present invention to obtain a one-pulse receiving direction finding radio wave specification analyzer capable of performing a direction search and a radio wave specification analysis using pulses.

[0006]

A one-pulse receiving radio wave specification analyzer according to the present invention receives arriving radio waves from a plurality of radio sources and outputs each received wave from an output terminal determined for each direction. A direction finding device to be output, and a plurality of radio wave specification analyzers connected to each of the output terminals of the direction finding device and measuring radio wave characteristics of the received wave in a predetermined direction output from the output terminal are provided. It is a thing.

[0007]

According to the present invention, the one-pulse receiving method specification analyzer outputs a received wave to an output terminal for each direction without depending on the frequency of a radio wave received by a receiving antenna, and outputs a radio wave connected to each output terminal. The received wave is output to the specification analyzer.
