The range resolution of pulse-Doppler radar refers to its ability to distinguish two closely spaced targets along the radial distance (range) of the radar transmitter and receiver. It is determined by the pulse duration or pulse width of the radar signal. In pulse-Doppler radar, range resolution is typically achieved by using short pulses, resulting in a sharper time domain response.
This allows the radar system to accurately measure the distance to a target, particularly useful in applications where precise discrimination and target discrimination are essential, such as in air traffic control, weather monitoring and military surveillance.
Range resolution in radar refers to the ability of the radar system to distinguish between two or more targets that are located close to each other along the radial distance (range). It is determined by the pulse duration of the transmitted radar signal.
A shorter pulse duration provides better range resolution because it produces a narrower main lobe in the radar’s range response function. This allows the radar to resolve closely spaced targets as separate entities, improving the accuracy of target detection, localization and tracking.
Range resolution is a fundamental parameter in radar design and operation, influencing the system’s ability to discern fine details in target positions and shapes.
Range resolution PRF (pulse repetition frequency) refers to the relationship between the pulse repetition frequency of the radar system and its range resolution capability. The PRF affects the range resolution because it determines the time interval between successive radar pulses. A higher PRF allows for shorter pulse intervals, which in turn improves the radar’s ability to resolve targets along the range axis.
By adjusting the PRF, radar operators can optimize range resolution based on specific application requirements, balancing between achieving fine resolution and maintaining an adequate target detection range. This parameter is essential in pulse doppler radar systems used in surveillance, tracking and remote sensing applications where accurate range measurement is essential
