Unveiling Lakeda Products: A Comprehensive Analysis of the Second-Level Response Mechanism from Command to Alert

In vast offshore areas, security threats such as smuggling, illegal intrusions, and fishing disputes are increasingly prevalent. Traditional radar systems struggle to adapt to the complex and ever-changing marine environment. Phased-array offshore security radar, as an advanced electronic scanning detection system, is becoming the “electronic neural network” safeguarding maritime security. Through the coordinated operation of hundreds of miniature antenna units, it achieves high-precision, all-weather detection, tracking, and identification of surface targets, providing robust support for offshore security.

1. What is Phased-Array Offshore Security Radar?

Phased-array radar, also known as electronically scanned array radar, utilizes multiple independent antenna units to form directional beams by controlling the phase of each unit. This enables high-speed scanning and multi-target tracking without mechanical rotation. This technology is particularly suitable for complex and dynamic offshore monitoring scenarios.

After the console issues a detection command, the radar system completes the entire signal processing cycle of “transmission—reception—processing—output.” Each step is optimized for the unique offshore environment, effectively suppressing sea clutter and electromagnetic interference while accurately extracting target information.

2. Core Debugging and Parameter Configuration

2.1 Operating Frequency Band and Installation Calibration

At the Wuhan radar-optic integrated system test site, after completing the radar installation, Lakeda technicians first perform precise orientation calibration. Since the radar’s detection performance is strongest along its normal direction, and detection capability weakens with an increase in elevation angle, it is essential to ensure coverage of key water areas.

Basic parameters such as radar orientation, target detection range, azimuth, and latitude/longitude are then entered, providing a data foundation for subsequent monitoring.

2.2 Threshold Configuration and Anti-Interference Optimization

Setting appropriate detection thresholds is crucial for ensuring recognition capability and minimizing false alarms. Lakeda technicians configure thresholds based on different target types, effectively distinguishing real targets from interference signals and significantly enhancing system reliability.

3. Dynamic Target Information Locking Mechanism

Lakeda offshore security radar employs electronic scanning directionality, Doppler effect analysis, and multi-dimensional data tracking to establish a comprehensive target parameter calculation system:

Target Bearing: Precisely calculates target azimuth and elevation angle based on electronic scanning and phase control.
Sailing Speed: Uses Doppler shift to compute radial velocity, combined with space-time adaptive processing to filter out sea wave interference.
Navigation Path: Utilizes high-density sampling and AI trajectory prediction algorithms, integrating AIS and electro-optical sensor data to eliminate false alarms and predict trajectories for the next 1–5 minutes.

4. Echo Reception and Anti-Interference Technology

In offshore environments, radar electromagnetic waves are susceptible to interference from sea waves, birds, etc. Each receiving unit of this radar can independently capture echo signals, using AI algorithms to filter out noise before achieving in-phase signal superposition through phase calibration. This “multi-unit synthetic gain” technology ensures stable output of high-precision target information even in harsh conditions.

5. Radar-Optic Integrated System: Multi-Sensor Collaborative Monitoring

Radar-Optic Integrated System in Action

A single radar system struggles to achieve all-weather visual monitoring. Lakeda innovatively integrates electro-optical sensors to launch a multi-dimensional monitoring system—the radar-optic integrated system:

Daytime Scenarios: Electro-optical sensors capture clear images of vessel appearances and identification numbers with high-resolution imaging.
Night and Low-Light Conditions: Infrared thermal imaging technology, unaffected by light or fog, identifies engine heat sources and hull outlines, enabling all-weather visual tracking.

6. Intelligent Zone Alert and Active Defense

Zone Monitoring Interface

To address illegal intrusions and fishing disputes, Lakeda’s radar-optic integrated system and “Lei Dun” fishery protection system support customizable alert zones and establish an active defense mechanism:

Zone Delineation: Precisely sets boundaries and alert levels for no-fishing zones, port control areas, and aquaculture zones.
Real-Time Comparison: The system compares radar and electro-optical data with preset zones in real time to identify unauthorized targets.
Multi-Level Alerts: Upon detecting intrusions, audio-visual alarms are triggered immediately, and target images, trajectories, and other information are pushed to the monitoring center, achieving closed-loop management of “detection—alert—response.”

7. Broad Applicability and Technical Advantages

This radar system features a high data refresh rate, enabling stable tracking of high-speed moving targets (such as “Da Fei” and speedboats). Its range covers 1.2 km to 8 km, making it suitable for various applications including ports, nearshore areas, and open waters.

Conclusion

Phased-array offshore security radar not only constructs an intelligent, all-weather marine “electronic neural network” but also plays a critical role in anti-smuggling operations, interception of illegal intrusions, and protection of fishery resources. It provides high-precision, highly reliable security assurance for marine ecological conservation and coastal economic development.
