RADAR is mostly Antennae, Radio hardware, Display hardware, Communication hardware, and Signal Processing. All but the most eccentric Engineer/Scientist has a thorough grasp of the considerable depth and breadth of RADAR Signal Processing. A PHD is not enough; study, study, study, that is the secret. Where RADAR was birthed in the single mode Analog world of Spark Gap transmitters, huge tubes, and Long Wave propagation, modern RADAR is almost completely Digital [Digital Signal Processing and Software Defined Radio], Multimodal, and MIMO (Multiple Input and Multiple Output (Refers to Antennae and Tuners)). Low cost, high speed personal computers able to leap tall buildings in a single bound provide unprecedented opportunity, opening a whole new country of consumer products as yet unexplored.
