BISTATIC RADAR Meaning and
Definition
-
Bistatic radar is a type of radar system that utilizes two separate physical locations to perform its operations. Traditionally, radar systems consist of a single site consisting of a transmitter and a receiver. However, in bistatic radar, the transmitting and receiving components are positioned at different locations. This characteristic introduces a range of advantages and capabilities not found in traditional radar systems.
In a bistatic radar system, the transmitter and receiver can be separated by varying distances, creating a larger baseline. This allows for improved resolution and accuracy in target detection. The increased baseline provides enhanced angular resolution, better target discrimination, and improved target tracking capabilities.
Another advantage of bistatic radar is its increased immunity to jamming and interference. By separating the transmitting and receiving elements, the radar system becomes less susceptible to countermeasures. In addition, bistatic radar can provide reduced vulnerability to detection and anti-radar missile threats.
Bistatic radar systems can be classified into two main configurations: forward-scatter and multistatic. In forward-scatter, the target reflects the radar signals directly to the receiver, resulting in a relatively simple setup. On the other hand, multistatic bistatic radar involves multiple transmitters and receivers, providing even more advantages in terms of multiple perspectives and increased coverage.
Overall, bistatic radar offers unique capabilities and advantages in target detection, tracking, and resilience to countermeasures. Its ability to separate transmitting and receiving components, along with its enhanced resolution and immunity, make it a valuable tool for military and civilian applications alike.
Etymology of BISTATIC RADAR
The word "bistatic radar" combines two main components: "bi-" and "radar".
- The prefix "bi-" comes from the Greek word "bi-", meaning "two" or "double". It indicates that the radar system involves two separate and distinct components or locations.
- The term "radar" is an acronym for "radio detection and ranging". It was initially coined in the 1940s to describe a technology that uses radio waves for detecting and locating objects in the environment.
Therefore, "bistatic radar" refers to a radar system that uses two separate locations for transmitting and receiving radio waves to detect and track objects.
