Akuisisi Data Sederhana Untuk Radar FM-CW

This paper describes the development of a simple data acquisition modul for FM-CW radar. The modul is design to be integrated in a through wall radar system using UWB and FM-CW technologies for life detector application. It uses a CY7C68013A, an EZ-USB family IC, from Cypress Semiconductor which is operated in slave FIFO mode. A Max II CPLD IC EPM1270T144 from Altera is used as a FIFO master. While for ADC, an AD9235 from Analog Devices is used. The modul is used to convert analog beat signal into digital data at a sampling rate of 1Msample/s and a resolution of 12 bit per sample

Ultra-wideband phased array radar for short-range imaging applications

Includes abstract.Includes bibliographical references (p. 105-108).Ultra-wide band (UWB) technology, as defined by the Federal Communication Commission (FCC) on February 2002, refers to signals or systems that have bandwidth ≥500 MHz or instantaneous fractional bandwidth ≥0.20 [2]. Compared to the conventional narrowband radar that operates with the same centre frequency, UWB radar offers many advantages, including high spatial resolution, for detecting closely-spaced target; and lower probability of interception, for stealth-like military application. There are many types of UWB waveform. The most obvious and simplest-to-generate UWB waveform is the impulse or short pulse. The pulse width of these impulses is usually sub-nanosecond, which enable a range resolution of 15 cm or less, when it is being transmitted in free space

Evaluation of crosstalk robustness of optical OFDM

The OFDM technology has been highly studied/investigated in the telecommunications field but it is still a relatively new term in the optical communications. OFDM has been evaluated in various studies although the tolerance against linear intrachannel crosstalk (XT) remains an open issue. This kind of XT is really relevant in several situations, for example in the multicore fibers (MCF), which is a new kind of fiber that intend to replace the current mono-mode fibers. Then, by using the VPI Photonics software several simulations will be done in different situations in order to see the effect of the Crosstalk on OFDM signals in a supposedly ideal transmitter-receiver system. To make a complete study, various simulations will be carried out changing the number of subcarriers, the order and the kind of the modulation used. The Crosstalk will be simulated by an interfering transmitter superposed to the main signal. By using an attenuator, we will be able to control the interference level that produces. The receiver will evaluate the impact of XT in terms of its sensitivity, so that the different cases can be analysed and later make conclusions. As for the OFDM parameters, we will work with 16, 64, 256 and 1024 subcarriers, and with 4-QAM and 16-QAM modulations.La tecnlogía OFDM ha estado muy estudiada/investigada en el campo de las telecomunicaciones pero todavía se trata de un campo nuevo en cuanto a las comunicaciones ópticas. OFDM se ha evaluado en varios estudios, aunque la tolerancia al crosstalk lineal intracanal (XT) es un tema abierto. Este tipo de XT es muy relevante en diversas situaciones, por ejemplo, en el context de las fibras multi-núcleo (MCF), un nuevo tipo de fibras que pretenden substituir las fibras mono-modo actuales. Así pues, mediante el software VPI Photonics se realizara un seguido de simulaciones en diferentes situaciones par ver el efecto del Crosstalk sobre señales OFDM en un sistema transmisor-receptor supuestamente ideal. Para realizar un estudio completo, se realizaran diferentes simulaciones variando el nombre de subportadoras, el orden y el tipo de la modulacion utilizada. El Crosstalk vendrá simulado por un transmisor interferente sobrepuesto a la señal principal, que mediante un atenuador, podremos controlar el nivel de interferencia que genera. El receptor evaluará el impacto del crosstalk en medidas de su sensibilidad, para poder analizar los diferentes casos y sacar conclusiones posteriormente. En cuanto a los parámetros del OFDM, trabajaremos con 16, 64, 256 y 1024 subportadoras, y con las modulaciones 4-QAM y 16-QAM.La tecnologia OFDM ha estat molt estudiada/investigada en el camp de les telecomunicacions però encara es tracta d?un camp relativament nou pel que fa a les comunicacions òptiques.
