DSMAC

1. 본문

DSMAC stands for Digital Scene Matching Area Correlator. It's a navigation and guidance technology, primarily used in missiles, that relies on comparing real-time images or sensor data with pre-loaded reference maps. Here's a breakdown of what DSMAC is and how it works:
Functionality:

• Image Matching: DSMAC's core function is to match live images captured by a sensor (like a camera or radar) during flight with reference images stored in its memory.
• Positioning: By comparing these images, the system determines the precise location of the platform (e.g., a missile).
• Guidance: This positioning information is then used to guide the platform to its target, making course corrections as needed.
• Terminal Guidance: DSMAC is often used in the terminal phase of a missile's flight, providing high accuracy for hitting the target. It can be combined with other guidance systems like TERCOM (Terrain Contour Matching) and GPS.

How it Works:1. Reference Map Creation: Before a mission, detailed maps of the target area are created, often using satellite or aerial imagery. These maps can be optical (using visible light) or radar-based.

2. Onboard Sensor: During flight, the platform uses a sensor (optical camera, radar) to capture images of the terrain below.

3. Image Correlation: The onboard DSMAC system compares the live images from the sensor with the pre-loaded reference maps. It looks for matching patterns and features.

4. Position Determination: By finding the best match, the system pinpoints the platform's location relative to the target.

5. Course Correction: If the platform is off-course, the guidance system uses the DSMAC data to make adjustments, ensuring it stays on track to the target.
Historical Context and Evolution:

• Early AI: DSMAC is considered an early form of Artificial Intelligence, demonstrating the ability to process visual information and make real-time decisions.
• Tomahawk Missile: The technology was initially developed for the Tomahawk cruise missile and played a significant role in the Gulf War.
• Modern Systems: Modern DSMAC systems have benefited from advances in solid-state technology (like CCDs) and increased computing power. They can store numerous images and even use image synthesis techniques.

Other uses of the acronym DSMAC:

• Immunology: In immunology, DSMAC, along with cSMAC, and pSMAC refers to areas of active membrane movement.
• Health Data Management: In the field of health informatics, there's a system called "Decentralized Self-Management of data Access Control" (DSMAC) that utilizes blockchain technology for secure and privacy-preserving management of medical data access.
