Pulse-repetition frequency (PRF) is the number of times a pulsed activity occurs every second. This is similar to cycle per second used to describe other types of waveforms. PRF is inversely proportional to time period T {\displaystyle \mathrm {T} } which is the property of a pulsed wave.

prf和pri的含义是什么，它们之间有什么关系？ 答：PRF—pulse repetition frequency， 脉冲重复频率 ； PRI—pulse repetition interval， 脉冲重复间隔 ，下图中的 T 就是PRI。

2021年1月3日 · 在这种分类中，雷达根据脉冲重复频率（prf）分为低prf、中prf和高prf雷达。 低PRF雷达主要用于测距，而对目标速度（多普勒频移）不感兴趣。 高PRF雷达主要用于测量目标速度。

2022年11月14日 · 雷达脉冲重复频率（Pulse Repetition Frequency，简称PRF）是雷达系统的一个重要参数，它决定了雷达发送脉冲的速率。 在Matlab中，你可以使用仿真功能来创建PRF对信号影响的斑马图，这通常用于理解 雷达 系统的采样率和回波特性。

The number of pulses transmitted in one second is called the "frequency", and is most often referred to as the "PRF" (pulse repetition frequency). The "duty ratio" (often called the Duty Cycle) is the ratio of the pulse width (PW) to the pulse repetition frequency (PRF), and is given by...

2020年12月3日 · 脉冲重复频率（PRF）是雷达脉冲发射的速度，即雷达每秒发射脉冲的个数，机载雷达的PRF可以从几百Hz到几百kHz，并且在雷达工作过程中可以改变。PRF的选择很重要，这是因为，它决定了雷达是否会产生距离模糊和多普勒频率模糊，以及模糊的程度。

Pulses at a fixed interval of time arrive at a rate or frequency referred to as the pulse repetition frequency (PRF) of so many pulse per second. Pulse repetition interval (PRI) and PRF are reciprocals of each other.

The waveform of a pulsed radar is usually represented by the pulse duration τ, the pulse repetition interval (PRI) T, or the pulse repetition frequency (PRF) f p. PRI is the time interval between two adjacent pulses. PRF is the rate that pulses repeat per second and is equal to the inverse of PRI.

2017年8月12日 · The radar signal characteristics of PW, PRI, PRF, and power determine the maximum range and the range resolution capability of specific radar. When combined with the frequency of the carrier wave of the radar signal, these parameters provide a unique signature to identify a specific radar signal.

2014年2月4日 · This document provides an introduction to pulse repetition interval (PRI) analysis and deinterleaving from an electronic intelligence (ELINT) perspective. It discusses key concepts such as PRI, unambiguous range and velocity, range-velocity ambiguity, optimum PRI for medium PRF radars, and PRI stagger.
