The application field and working principle of ASCANCS (Auto Surveillance and Characterization of Spacecrafts) are extensively studied in the field of RF antennas. The technology is used to accurately detect and track spacecrafts (SC) in the Earth\'s orbit. ASCANCS provides a unique method to detect and track spacecrafts using a combination of active and passive sensing techniques.

The active sensing techniques use RF antennas to detect SCs by sending out an electromagnetic wave that is reflected back from the spacecraft, providing its position and velocity information. The passive sensing techniques use a wide range of sensors to detect SCs, such as optical and infrasonic detectors. The active and passive techniques are combined to produce an accurate picture of the SCs in orbit.

The advantages of ASCANCS technology are many. It is able to track multiple SCs simultaneously, and its accuracy can reach to within a few meters. Furthermore, it can accurately identify different types of SCs, such as communications satellites, navigation satellites, and research satellites. Additionally, ASCANCS can detect and track objects in low, medium, and highly elliptical orbits.

The ASCANCS technology is also used for military applications, such as surveillance of enemy targets and hostile forces. It can detect and track aircrafts with high accuracy, as well as ground based targets. In addition, it can detect and characterize potential hostile activities, such as missile launches and troop movements.

The working principle of ASCANCS technology involves a combination of both active and passive sensing techniques. The active sensing uses an RF antenna to send out an electromagnetic wave that is reflected back from the spacecraft. The reflected signal is then collected and analyzed to detect and track the spacecraft.

The passive sensing techniques use a variety of sensors, such as optical cameras, infrasonic detectors, and laser rangefinders, to monitor and detect SCs. These sensors are used to detect subtle changes in the signal, such as a change in the frequency spectrum due to a spacecraft passing overhead, or a sudden change in acceleration or velocity.

The data collected by the various sensors is then used to accurately identify and track spacecrafts. The data is analyzed and compared with stored information to provide an accurate description of the spacecrafts in orbit.

In summary, ASCANCS is a unique technology that combines active and passive sensing techniques to accurately detect and track spacecrafts. It is used in a variety of applications, including military, research, and communications. The working principle involves using an RF antenna to detect SCs and other passive sensors to detect subtle changes in the signal. The data collected is analyzed and compared with stored information to provide an accurate description of the spacecrafts in orbit.
