DETECTION AND TRACKING RADAR, ANTI HIGH SPEED MOBILE DEFENSE SYSTEM HAVING THE SAME AND HIGH SPEED MOBILE TRACKING METHOD OF DETECTION AND TRACKING RADAR
First Claim
1. A detection and tracking radar comprising:
- a hazardous zone set within a preset radius based on a main body having a radar;
a plurality of detection and tracking sectors configured to detect a high speed mobile approaching the main body within detection areas, the detection areas being defined by diving the hazardous zone based on an azimuth angle; and
a controller configured to recognize the high speed mobile as a target based upon signals received from the detection and tracking sectors and track the target,wherein each of the detection and tracking sectors comprises;
a transmit antenna unit and a transmitting unit configured to radiate a Continuous Wave (CW) or Linear Frequency Modulation (LFM) type waveform signal; and
a receive antenna unit and a receiving unit configured to receive the waveform signal reflected from the high speed mobile,wherein the transmit antenna unit, the receive antenna unit, the transmitting unit and the receiving unit are integrally formed for each detection and tracking sector.

Abstract
A detection and tracking radar includes a hazardous zone set within a preset radius based on a main body having a radar, a plurality of detection and tracking sectors configured to detect a high speed mobile approaching the main body within detection areas, the detection areas being defined by diving the hazardous zone based on an azimuth angle, and a controller configured to recognize the high speed mobile as a target based upon signals received from the detection and tracking sectors and track the target. Accordingly, rapid detection and tracking of the high speed mobile can be allowed. Also, since the detection and tracking sectors can be independently run, expansion of a radar system can be free by virtue of addition of the detection and tracking sectors.

11. A method for tracking a high speed mobile in a detection and tracking radar comprising:
-
receiving a Continuous Wave (CW) or Linear Frequency Modulation (LFM) type reflection signal for each of detection and tracking sectors, divided in plurality; generating burst data by multiplying the received signal by a preset window function; generating a frequency conversion data by performing a Fast Fourier Transformation (FFT) with respect to the burst data; detecting data exceeding a preset threshold value from the frequency conversion data, the threshold value set to have a specific false alarm rate; recognizing the detected data as a target when the detected data meets a preset condition; and converting a coordinates system of a second detection and tracking sector, adjacent to a first detection and tracking sector, into a coordinates system of the first detection and tracking sector for continuity of movement information relating to the high speed mobile. - View Dependent Claims (12)

13. A high speed mobile defense system comprising:
-
a main body; a hazardous zone defined within a preset radius based upon the main body; a plurality of detection and tracking sectors configured to detect a high speed mobile approaching the main body within detection areas, the detection areas being defined by diving the hazardous zone based on an azimuth angle; and a controller configured to recognize the high speed mobile as a target based upon signals received from the detection and tracking sectors and track the target, wherein the controller comprises a coordinates conversion module configured to perform a coordinates conversion for continuity of movement information relating to the high speed mobile when the high speed mobile being tracked within a first detection area moves into an adjacent second detection area.
