A high PRF is also a disadvantage, which means it has a limited distance to perform unambiguous determination of range.

Conversely, a high PRR/PRF can enhance target discrimination of nearer objects, such as a periscope or fast moving missile. How do you increase PRF on …
WebIn high PRF pulse Doppler radars, SNR is usually calculated by using the centerline power of the transmitted signal spectrum as the target return power because the centerline is kept in the receiver and returns of the PRF lines are notched out [1]. WebHigh PRF's (more rapid pulses meaning less listening time between pulses) greatly improve the radar's ability to determine velocity. Yet, it also increases the number of second or third trip echoes. What this means is the radar …

The scanner rotation cannot be too fast otherwise the pulses may miss a target. Therefore a long range radar with a low PRF must have a slow scanner rotation. But a short range high PRF radar may have a high scan rate to rapidly update the image. crystal rish
