Pulse radars are mostly designed for long distances and transmit a relatively high pulse power. Important distinguishing feature to other radar method is the necessary time control of all processes inside the pulse radar. The leading edge of the transmitted pulse is the time reference for the runtime measurement.

A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics.

2025年3月21日 · Radar - Pulse, Detection, Reflection: The most common type of radar signal consists of a repetitive train of short-duration pulses. The figure shows a simple representation of a sine-wave pulse that might be generated by the transmitter of a medium-range radar designed for aircraft detection.

Radar Functions • Normal radar functions: 1. range (from pulse delay) 2. velocity (from Doppler frequency shift) 3. angular direction (from antenna pointing) • Signature analysis and inverse scattering: 4. target size (from magnitude of return) 5. target shape and components (return as a function of direction) 6. moving parts (modulation of ...

Explore the fundamentals of pulse radar systems, including their operation, advantages, and applications in various fields. Learn about pulse radar systems, their mechanisms, and how they are applied in real-world scenarios.

2024年5月21日 · Pulse radar is a well-known method of detecting objects by emitting short pulses of radar energy into space and then detecting the energy that bounces back after it hits an object. To determine the object’s distance, the radar system measures the length of time a pulse travels to and from the object.

2011年5月28日 · What is a pulse doppler radar? Measuring round trip return timing is fundamental to radar, but it can be difficult to distinguish returns from the target of interest and other objects or background located at similar distances. The use of Doppler processing allows another characteristic of the return to be used – relative velocity.

2024年11月5日 · 多普勒脉冲雷达（Doppler Pulsed Radar，DPR）是一种利用多普勒效应测量目标速度的雷达系统。它发射一系列脉冲波，并接收目标反射回来的回波信号。通过分析回波信号的频率变化，可以计算出目标的速度。

Pulsed radar entails the transmission of a succession of radio frequency (RF) pulses. As noted in Chapter 1, pulse modulation enables the range of a target to be measured. Pulsed modulation also permits a high-power transmitter to be used, which helps achieve a long detection range.

Pulsed radar, or pulsed time-of-flight, is similar to the ultrasonic method of level measurement. A radar pulse is aimed at the surface of the substance being measured and the time for the pulse to return is used to find the level.
