Pulse Doppler filtering on groups of 8 or greater pulses with a fine grained clutter map. Aircraft are detected in ground clutter and / or rain with the Doppler filter bank & use of 2 PRFs. Courtesy …

By making the radar coherent, the phase history of the target can be preserved during the coherent processing interval (CPI), so that Doppler information can be derived, which provides …

Moving Target Indicator (MTI) and Pulse-Doppler (PD) processing use the Doppler shift of the different signals to enhance detection of moving targets and reject clutter. Unambiguous range …

为简单起见，我们假设目标的雷达散射截面（ radar cross sections, RCS）包含在相干处理间隔（coherent processing interval, CPI）期间不波动的单点散射体。 鉴于CPI不是很长， 可以安 …

In a pulse radar system, coherence describes the phase relationships between the transmitted and the received pulses. Oscillations and electromagnetic waves are described as coherent if …

一组以某种方式相干组合的脉冲，对于例如通过多普勒处理或 合成孔径雷达 （SAR）成像，形成了一个相干处理间隔（CPI）。 更高的水平雷达处理作用于来自多个 CPI 的数据，因此在甚至 …

The radar detectability factor is the minimum signal-to-noise ratio (SNR) required to declare a detection with the specified probabilities of detection, P d, and false alarm, P f a. The Modeling …

2022年11月14日 · 恒虚警率CFAR是Constant False-Alarm Rate的缩写。 在雷达信号检测中，当外界干扰强度变化时，雷达能自动调整其灵敏度，使雷达的 虚警概率 保持不变，这种特性称为 …

The key to understanding velocity resolution for pulsed radar is that coherent processing interval (CPI - the total amount of time spanned by slow time samples) acts as a rectangular …

2011年6月10日 · Coherent processing interval (CPI) The number of N columns is the number of transmit pulses in the coherent processing interval (CPI). Recall that all of the radar data is …
