1995年5月20日 · A test target simulator (TTS) based on a fiber-optic delay line (FODL) has been designed for realistic testing and characterizing of wideband pulsed Doppler radars. The TTS …

基本的思路是：k-fold CV，也就是我们下面要用到的函数 KFold ，是把原始数据分割为K个子集，每次会将其中一个子集作为测试集，其余K-1个子集作为训练集。

Figures 3 to 5 are the Miteq’s FODL performance measured by the manufacturer prior to shipping the system to NRL, including a relatively flat throughput loss from 1 to 5 GHz (Figure 3), a …

A FODL can also be utilized to emulate range in radar testing such as depicted in Figure 2. In this scenario, a transmitted radar signal impinges on a target at a fixed range and the returned …

2015年1月14日 · FODLs have been used for several decades to test radar systems, measuring phase noise and simulating reproducible signals for outdoor range testing. These small, …

2013年1月15日 · One of the most compact, accurate and reliable is the Fiber Optic Delay Line (FODL) method. The FODL method exploits the small size, lightweight, low loss and low drift …

FODL (fiber optic delay line) systems eliminate the need for expensive and time-consuming outdoor range tests for radio and radar systems. This white paper outlines how FODL …

2024年8月23日 · ODLs are fundamental in interferometric measurements, where precise path length differences are introduced to measure physical quantities like distance, displacement, …

2015年12月25日 · To improve the performance of optical delay line devices, a Fast Optical Delay Line (FODL) device was designed on the basis of the principle of involutes. After analysis of …

The FODL-1600/3200 datalogger is capable of measuring the absolute cavity length of Fabry-Perot fiber optic transducers with great accuracy, providing highly reliable measurements. It is …
