Radio Frequency Pulse Compression*

Using Time Sidelobe Measurements to Assess the Performance of Compressed-Pulse Radars

Unfortunately, traditional RF pulse measurements become less effective predictors of performance in radars that use pulse compression. For example, the width of an uncompressed radar pulse is directly related to spatial resolution. In contrast, the resolution depends on pulse width, chirp bandwidth and chirp linearity in a compressed radar system that uses linear frequency modulated (LFM) chirp...

Real Time Implementation of Digital LFM Pulse Compression Technique over Acoustic Waveguides

This paper presents the implementation of Linear Frequency Modulation (LFM) pulse compression technique over acoustic waveguides at frequency range (2kHz--3kHz). The medium used for acoustic chirp propagation is air. Real time pulse compression was carried out over DSP kit (TMS320C6713). The obtained range from the compressed pulse accedes to the actual range of the target (sound source). The s...

Active High-Power RF Pulse Compression Using Optically Switched Resonant Delay Lines

Traveling Wave Undulators for FELs and Synchrotron Radiation Sources

We study the use of a traveling wave waveguide as an undulator for short wavelength free-electron lasers (FELs) and synchrotron radiation sources. This type of undulator -which we will call TWUcan be useful when a short electron oscillation period and a large aperture for the propagation of the beam are needed. The availability of high power X-band microwave sources, developed for the electron-...

Waveguide System ‘ to Accelerator I Cavities Multiplier

Proposed future positron-electron linear colliders’ would be capable of investigating fundamental processes of interest in the 0.5-5 TeV beam-energy range. At the SLAC Linear Collider (SLC) gradient of about 20 MV/m this would imply prohibitive lengths of about 50-250 kilometers per linac. We can reduce the length by increasing the _ gradient but this implies high peak power, on the order of 40...
