Electromagnetic Radiation, RF Pulses and RadarA radar transmitter generates multiple forms of electromagnetic energy. This energy is amplified and transmitted and ultimately is reflected off a target, received and the difference in time and frequency of the transmit signal verses the received signal is used to determine the distance and velocity of a target.Referring to figure 1; a pulse of...

Application Note: Benchmarking electronic calibration of USB-enabled Network Analysers
Authors: James Skinner & Nick Ridler, National Physical LaboratoryNils Nazoa, LA Techniques LtdMark Ashcroft, Pico Technology AbstractThese days, many instrument calibrations are performed automatically – for example, using electronic calibration units. This includes calibration of vector network analysers (VNAs) where the calibration standards are generated electronically rather than using mechanical devices. However, verifying performance – particularly accuracy – of these... -
Application Note: Proteus Radar Target Simulator
This document describes how to implement a Radar Target Simulator/Generator using the Tabor Electronics’ Proteus AWT (Arbitrary Waveform Transceiver). The Proteus AWT RTS system is a configuration of the Proteus AWT that is design to receives a signal from the Radar under test and performs real time calculations in its internal FPGA to simulate a moving target. High level FPGA... -

The importance of vibration control in the machining and metrology of advanced aspheric optics
Aspheric optics are commonly used in advanced optical systems, such as AR/VR headsets, surveillance systems and semiconductor applications, to minimize size, weight, and cost. Achieving the required level of performance requires stringent control in the machining and metrology of the optics. One of the manufacturing tools used to make precision aspheres is a single point diamond turning lathe like those... -
Metal Coating of Styrofoam (XPS) and Polystyrene Foam (EPS) Samples for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY STYROFOAM? SEM imaging is an ideal tool to check the size and homogeneity of the cells in the polymer foam structure, and if the material has a closed or open cell structure. Other elements that can be studied are the foaming and cell formation efficiency, and how different agents influence these processes. Chemical... -
Metal Coating of Glass Fibres for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY GLASS FIBRES? SEM imaging is an ideal tool to check the homogeneity, compactness aof glass fibres in a polymer matrix. Other defects such as poor adhesion of the fibres to the polymer matrix (shown as clean fibres) can also easily be detected. Chemical microanalysis techniques (EDS) used in conjunction with scanning electron microscopy... -
Metal Coating of Nanofibres for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY NANOFIBRES? SEM imaging is an ideal tool to check the homogeneity and diameter of nanofibres. SEM manufacturers have developed specific software applications for a fully automatic fibre diameter distribution measurement. Nanofibres are also used in air filtration applications for antibacterial and nanoparticle applications. SEM imaging (eventually combined with EDS chemical microanalysis techniques) to... -
Metal Coating of a Face Mask for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY FACE MASKS? SEM imaging is an ideal tool to check the homogeneity, compactness and average diameter of fibres in the different face mask layers. The SEM image show a 10nm gold coated non-woven polypropylene filtration layer at 1400x magnification. Some SEM manufacturers have developed specific software applications for a fully automatic fibre diameter...
