Analysis of Automatic Target Recognition Technology for Anti-Drone Radar: Principles and Practical Guide

Fri, 29 Nov 2024 00:00:00 +0800

In recent years, with the increasing threat posed by Low Slow Small (LSS) drones, the demand for counter-unmanned aerial vehicle (radar) systems has become increasingly urgent [1-3]. However, whether in academic research or practical applications, technical discussions regarding such radar systems still face numerous unresolved challenges. A variety of counter-drone radar systems have emerged on the market, many claiming excellent performance in drone echo detection, with some systems already procured and deployed at critical sites. Nevertheless, multiple government agencies remain cautious about their actual effectiveness and have initiated several verification projects to assess their reliability.

Beginner's Guide to Radar: Mastering Core Basics from Scratch

Mon, 24 Jun 2024 00:00:00 +0800

What is Radar?

Radar (RADAR) is an acronym for “Radio Detection and Ranging.” It is a key technology that uses radio waves to detect objects and determine their spatial positions. In November 1940, U.S. Navy Commanders Samuel M. Tucker and F. R. Furth first formally proposed the term “radar,” which is why it is also widely referred to as a “radio positioning system.”

Historical Development of Radar

Origins and Early Applications

Radar technology dates back to World War I. At that time, the British military urgently needed a technology capable of detecting airborne metal objects to counter the threat of German air raids. During World War II, radar technology experienced rapid development, gradually giving rise to various functional systems such as ground-to-air, air-to-ground bombing, air-to-air fire control, and friend-or-foe identification.

Perimeter Security System: Core Functions, Application Scenarios, and Selection Guide

Wed, 06 Mar 2024 00:00:00 +0800

System Background

With the continuous improvement of national security standards, traditional perimeter protection methods can no longer meet the requirements of high-security areas. Most domestic sites still rely on passive defense methods such as manual patrols, wire mesh fences, vibration fiber optics, and video surveillance. These approaches have significant limitations: they cannot provide early warning of intrusions, struggle to adapt to complex terrains and ultra-long perimeters, and lack the ability to predict and actively respond to emergencies.

Comprehensive Analysis of Radar Operating Frequencies: Principles, Classification, and Application Guide

Sat, 08 Jul 2023 00:00:00 +0800

According to the basic working principle of radar, any system that detects and locates targets by transmitting electromagnetic energy and utilizing the reflected echoes falls within the scope of radar, regardless of its transmission frequency. Common radar operating frequencies typically range from 220 MHz to 35,000 MHz, but in practice, many radar systems may operate outside this range. For example, sky-wave over-the-horizon (OTH) radar can operate at frequencies as low as 4 MHz or 5 MHz, while ground-wave OTH radar can operate at frequencies as low as 2 MHz. At the higher end of the spectrum, millimeter-wave radar can reach 94 GHz, and lidar uses even higher optical frequencies. Radars operating at different frequencies exhibit significant differences in engineering design and implementation.
