We report on the use of a versatile 94GHz FMCW instrumentation radar to assess optimum hardware configurations for a variety of co-polar and cross-polar target classification studies. Phase noise and sweep linearity are critical parameters in FMCW radars and optimising them is a key objective of any high performance radar system. We have made a systematic comparison of fundamental sources (bias tuned...
The AVTIS radar developed in St Andrews is a ground-based, portable, 3D imaging radar designed for high resolution terrain mapping. The 94 GHz radar uses FMCW modulation and employs a mechanically scanned monostatic antenna configuration, achieving a maximum range of ~7 km with sub-metre range resolution. We discuss the significant factors which affect the imaging performance such as source phase...
Pulse coherent radar and pulsed magnetic resonance spectrometry are closely related techniques which share similar design constraints and technological difficulties, despite the obvious differences in application. Millimetre wave pulsed electron spin resonance (ESR) spectrometry is a rapidly developing scientific technique which is at the forefront of pulse coherent mm-wave instrumentation. Our work...
