Study Notes
Radar Imagery vs. Optical Systems
- Radar imagery has an advantage over optical systems due to its ability to operate in various environmental conditions, such as fog, smoke, and darkness.
Primary Surveillance Radar (PSR)
- PSR is capable of detecting and tracking targets, but it lacks Doppler frequency shift measurement, making it unable to determine target velocity.
- The primary function of PSR is to detect and track targets, specifically for air traffic control.
Radar Wavelength
- Radar's specific wavelength allows it to penetrate atmospheric conditions, such as fog, smoke, and clouds, making it ideal for imagery acquisition.
RADAR Systems
- The primary function of RADAR systems is to detect and locate target objects using radio waves.
- The basic principle behind RADAR systems is that they transmit radio waves, which bounce back when they encounter a target, allowing the system to detect and locate the object.
Active Remote Sensing
- Radar's primary advantage as an active remote sensing system is its ability to operate in various environmental conditions, including fog, smoke, and darkness.
Development of Imaging Radar Systems
- The development of imaging radar systems in the 1950s was driven by the need for accurate battlefield surveillance.
Basic Types of Radar Systems
- There are two basic types of radar systems: Primary Surveillance Radar (PSR) and Secondary Surveillance Radar (SSR).
