1 is a block diagram showing the configuration of a radar system and a detection area scanning apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the radar system 10 includes a detection area scanning device 20 and an antenna 30.

The radar system 10 of the present invention is a device that detects more than a certain distance and 360 degrees while rotating periodically, emits electromagnetic waves, receives reflected electromagnetic waves, and analyzes a target from a detection area.

The radar system 10 may be a passive electronically scanning phased array (PESA) type system, and the passive electronically scanning phased array system has a feature capable of detecting all directions of 360 degrees faster than a mechanical rotating radar. However, the radar system 10 is not limited thereto.

The detection area scanning apparatus 20 of the present invention may include a data acquisition unit 100, a servo control unit 200, a phase shifter control unit 300, and a target detection execution unit 400.

The detection area scanning device 20 according to an embodiment of the present invention is a device that is applied to a tracking radar that tracks a target by detecting a signal reflected from a target to scan a detection area with an approximate position of the target. Mechanical and electronic beams are used together to scan an area. The tracking radar to which the detection area scanning device is applied can be mounted and operated on the vehicle and the guided projectile.

The detection area scanning device 20 performs a detection area search for detecting a target from a radar, and is applied to a radar used to quickly and accurately detect the location of enemy ships, vehicles, and tanks, and track and shoot down the detected target. I can.

The data acquisition unit 100 according to an exemplary embodiment of the present invention may determine a detection area using target information received from the outside and location information of a current radar, and obtain data on scan information. The scan information may include a minimum dwell time for target detection, a foot-print value, an elevation direction footprint value, a gimbal steering angle, and gimbal scan speed. A detailed description of acquiring data will be described later through FIGS. 2 to 3B.

The servo control unit 200 according to an exemplary embodiment of the present invention may generate a control signal for steering a mechanical beam for scanning a detection area.

The servo control unit 200 may control the steering of the mechanical beam by generating a servo control signal that controls the driving of the mechanical gimbal. Here, the servo control signal can control the angle of the mechanical gimbal based on the gimbal steering angle calculated by the data acquisition unit 100, and control to scan in a raster scan method by applying the gimbal scan rate (scan_rate). have. For example, if the elevation direction footprint value is less than 1, a control signal is generated to scan only one azimuth angle, and if the elevation direction footprint value exceeds 1, after completing the azimuth angle scan once, the elevation direction is performed using a raster scan method. It is possible to generate a servo control signal that scans up to the footprint value.

The phase shifter controller 300 according to an embodiment of the present invention may generate a phase conversion control signal for steering an electronic beam for scanning a detection area. Here, the phase conversion control signal is a control signal converted by a phase shifter, and if scanning starts at the upper electron beam steering angle and the calculation time per footprint (t _dwell ) is performed, the scan is performed by moving -1 degrees from the upper electron beam steering angle to the lower electron beam steering angle. It is possible to generate a phase conversion control signal to perform.

In addition, the phase shifter controller 300 may generate a control signal to match the vertical virtual line by correcting the azimuth angle based on a virtual line perpendicular to the mechanical beam scan direction for the array of inclined electron beams in the detection area. . For example, based on the mechanical beam scanning direction, the upper end of the prearranged electron beam is inclined 10 degrees to the right from a virtual line perpendicular to the mechanical beam scanning direction, and the lower end of the prearranged electron beam is perpendicular to the mechanical beam scanning direction. If it is inclined 10 degrees to the left from the line of, correct the upper end of the pre-array electron beam inclined 10 degrees to the right by 10 degrees to the left and correct the lower part of the pre-array electron beam tilted to the right by 0 degrees and 10 degrees to the right by By generating a control signal that corrects 0 degrees, the prearray electron beam arrangement can be corrected.

Specifically, the target detection execution unit 400 may form a target detection map and perform target detection using a target signal included in the reflected signal and a clutter signal other than the target. For example, after data rearrangement for forming a target detection map and shaking motion compensation and unnecessary clutter signals are removed using raw data on the reflected signal, the data may be interpolated and compressed to form a target detection map. Sampling data from which unnecessary clutter signals have been removed can be obtained using a curve fitting method. Next, after performing the vibration compensation on the sampled data, the target detection map may be formed by interpolating and compressing in the distance and azimuth direction. Since the curve matching method, the shaking motion compensation, and the method of interpolating and compressing data are generally well known, a detailed description thereof will be omitted, and a method of forming a target detection map is not limited thereto.

The antenna 30 may scan a detection area including an approximate position of a target according to a control signal for steering a beam. Here, the antenna 30 includes a gimbal device that rotates in azimuth and elevation directions to scan the detection area, and may be controlled by a servo control signal.

The antenna 30 scans the detection area by the servo control signal and the phase conversion control signal, and receives a signal reflected from the detection area. These reflected signals may include a target signal and a clutter signal other than the target.

2 is a block diagram illustrating a configuration of a data acquisition unit according to an embodiment of the present invention.

As shown in FIG. 2, the data acquisition unit 100 according to an embodiment of the present invention may include a detection area determination unit 110 and a scan information calculation unit 120.

The detection area determination unit 110 according to an embodiment of the present invention may determine the detection area using rough location information and target information of the target. The detection area can be finally determined based on the uncertainty of the radar target information. Here, the uncertainty of the radar target information means the inaccuracy of the initial target information provided from a ground detection radar or an artificial satellite. In an embodiment of the present invention, a wide detection area is covered.

The scan setting information calculation unit 120 according to an embodiment of the present invention may calculate scan setting information for scanning the detection area. The scan setting information includes a minimum irradiation time for target detection (Dwell Time), azimuth direction footprint value, elevation direction footprint value, gimbal steering angle, and gimbal scan speed. Here, the minimum irradiation time can be reduced or increased according to the radar reflection area (RCS) of the target and the radar system specifications, and must satisfy more than the minimum time that satisfies the signal-to-noise ratio (SNR) for detecting the target. For example, in the present invention, it is assumed to be 1 ms to 100 ms.

A specific method for calculating scan setting information will be described with reference to FIGS. 3A to 3B.

FIG. 3A is a view showing a footprint when a beam is steered downward from a radar equipped with a detection area scanning device according to an embodiment of the present invention, and FIG. 3B is a diagram illustrating a detection area according to an embodiment of the present invention. It is a diagram showing a radar equipped with a detection area scanning device in a situation where:

3A and 3B, the scan information calculation unit 120 according to an embodiment of the present invention provides a footprint when a beam is steered downward (Look-Down) from a radar equipped with a detection area scanning device. Scan setting information can be calculated using the relationship between the detection area and the radar equipped with the detection area scanning device.

Scan information can be calculated using the following [Equation 1].

Where t _dwell is the operation time per footprint, PRI is the pulse repetition period, NCI is the cumulative integral, N _CR is the azimuth direction footprint value, w is the search area azimuth direction length, θ _CR is the beam width azimuth length, and N _R is Elevation direction footprint value, h is the search area elevation direction length, θ _R is the beam width azimuth length, θ is the mechanical gimbal steering angle, and scan_rate is the total azimuth scan time or gimbal scan speed.

As for the pulse repetition period, among the pulse repetition periods available in the radar system, a pulse repetition period that can obtain a relative distance to the detection area without an uncertain area should be selected.

In consideration of [Equation 1] (a) for target detection, (e) of [Equation 1] for the detection region is determined. Here, the steering of the electron beam in the elevation direction must be considered.

In the azimuth direction, the beam width azimuth length θ _CR is θ _CR = Rθ _3dB . That is, if Rθ _3dB is obtained, the θ _CR value can be obtained. Here, R is the relative distance from the center of the detection area to the radar, and θ _3dB is the antenna beam width.

The beam width azimuth length θ _R in the elevation direction is θ _R = R((2N+1) θ _3dB ) cscψ _g . That is, N denotes the maximum electronic beam steering angle, and ψ _g denotes the grazing angle.

Here, the mechanical gimbal steering angle (θ) refers to the maximum mechanical gimbal steering angle that can cover all the azimuth length of the detection area with a footprint.

The scan setting information calculation unit 120 may transmit the scan setting information calculated using [Equation 1] to the servo control unit 200 and the phase displacement control unit 300.

4 is a flowchart illustrating an operation of a detection area scanning apparatus according to an embodiment of the present invention.

As shown in FIG. 4, in the operation of the detection area scanning apparatus according to an embodiment of the present invention, a signal for target detection may be received in step S410. Here, the signal for target detection refers to target information received from a ground detection radar or satellite, and the target information may include a distance to a target, a speed, a number of targets, and an approximate position of the target.

Next, in step S420, data on the detection area and scan information may be obtained using target information included in the received signal and location information of the current radar. The scan setting information may include a minimum irradiation time (Dwell Time) for target detection, an azimuth direction footprint value, an elevation direction footprint value, a gimbal steering angle, and gimbal scan speed.

Next, in step S430, a phase conversion control signal for steering the electronic beam may be generated using the scan setting information. Specifically, it is possible to generate a phase conversion control signal that scans for a minimum irradiation time from the upper electron beam steering angle of the phase shifter and then moves -1 degrees to the lower electron beam steering angle to perform the scan.

Next, in step S440, a servo control signal for steering a mechanical beam may be generated using the scan information. Specifically, a control signal for steering a mechanical beam may be generated by using the gimbal steering angle, azimuth scan speed, and elevation direction footprint values included in the scan information. For example, if the elevation direction footprint value is less than 1, a control signal is generated to scan only one azimuth angle, and if the elevation direction footprint value exceeds 1, after completing the azimuth angle scan once, the elevation direction is performed using a raster scan method. A control signal that scans up to the footprint value can be generated.

Next, the generated control signal is transmitted to the antenna 30, and in step S450, the antenna 30 may scan the detection area by the control signal and receive a signal reflected from the detection area.

Specifically, it is possible to scan a detection area by steering a mechanical beam and an electronic beam by a control signal, and receive a signal reflected by a target or a feature in the detection area.

Next, in step S460, target detection may be performed using a signal reflected from the detection area.

Specifically, the reflected signal includes a target signal and a clutter signal other than the target, and data rearrangement to form a target detection map using raw data about the reflected signal, vibration compensation, and unnecessary clutter signals are removed. After that, the data can be interpolated and compressed to form a target detection map.

5 is a flowchart illustrating an operation of a data acquisition unit of a detection area scanning apparatus according to an embodiment of the present invention.

As shown in FIG. 5, in the operation of the data acquisition unit of the detection area scanning apparatus according to an embodiment of the present invention, the target detection area may be determined based on the uncertainty of target information included in the received signal in step S421.

Next, in step S422, scan setting information including a minimum irradiation time, azimuth direction footprint value, elevation direction footprint value, gimbal steering angle, and gimbal scan speed may be calculated using the current radar location information and target information. Here, the minimum irradiation time refers to an operation time per footprint, and the gimbal scan speed can be calculated as the total azimuth scan time.

6 is a flowchart illustrating an operation of a detection area scanning apparatus according to an embodiment of the present invention in detail.

As shown in FIG. 6, the operation of the detection area scanning apparatus according to the embodiment of the present invention starts scanning at θ _M , which is the upper electron beam steering angle of the phase shifter in step S610.

Next, in step S620, the footprint irradiated by the steering angle of the phase shifter is scanned by t _dwell .

Next, in step S630, if the upper electron beam steering angle θ _M is the same as the lower electron beam steering angle θ _m , the process may proceed to step S650.

If the value of the upper electron beam steering angle θ _M is not the same as the lower electron beam steering angle θ _m , the upper electron beam steering angle θ _M is steered by -1 degrees and proceeds to step S620 to perform a footprint scan.

If the footprint scan from the upper electron beam steering angle of θ _M to the lower electron beam steering angle of θ _m is completed, a step of comparing N _R and i that is the elevation direction footprint value in step S650 may be performed. Here, i is a natural number greater than 1 and means moving by i in the elevation direction.

If the value of N _R exceeds the value i, the mechanical beam may be steered and moved by i+1 in the elevation direction (s660).

Next, the mechanical beam moving i+1 in the elevation direction may be scanned in a raster scan mode (S670).

Next, the scan may be performed again at the top electron beam steering angle θ _M of the phase shifter (S610).

When all the footprints of the detection area have been scanned, the scanning may be terminated (S680).

7 is an exemplary view showing a measurement result when a footprint value in an elevation direction is less than 1 in the detection area scanning apparatus according to an embodiment of the present invention.

As shown in FIG. 7, the detection area was assumed to be 27km x 27km and the tilt angle was 50 degrees, the mechanical beam steering limiting element was the gimbal scan speed, and the electronic beam steering limiting factor was set as the footprint calculation time (Dwell Time). .

7(a) shows a measurement result of scanning by mechanical beam steering, and reference numeral 710 denotes a single beam irradiation area. Therefore, since all detection areas were scanned with a single beam irradiation area, the maximum gimbal scan speed was 100 deg/s and the total scan time was 7.54 seconds.

7B shows a measurement result obtained by scanning using a mechanical beam and an electronic beam according to an embodiment of the present invention, and reference numeral 720 denotes an irradiation area of the mechanical beam and the electronic beam. Therefore, as the irradiation area increased, the gimbal scan speed was reduced to a maximum of 72 deg/s, and the total scan time was 0.8 seconds. Here, the azimuth direction scan was performed only once because the elevation direction footprint value was 1 or less.

8 is an exemplary view showing a measurement result when a footprint value in an elevation direction exceeds 1 in the detection area scanning apparatus according to an embodiment of the present invention.

As shown in FIG. 8, it is assumed that the detection area is 30 km x 30 km and the tilt angle is 70 degrees, and the limiting elements of mechanical beam steering and electronic beam steering are the same as those of FIG. 7. 8 shows the measurement results obtained by scanning using a mechanical beam and an electronic beam. When the elevation footprint value exceeds 1, performing azimuth scan once and then performing azimuth scan in raster scan mode. I can confirm. When the scan was performed by mechanical beam steering, the gimbal scan speed was at most 513 deg/s, and when the scan was performed with the present invention, the gimbal scan rate was measured at a maximum of 73.3 deg/s.

As described above, rather than scanning a detection area using only a mechanical beam, scanning by using a mechanical beam and an electronic beam together can reduce the motor overload and improve the scan speed.
