There should never be any doubt that designing and building sophisticated phased array active imaging systems is difficult, but the real difficulty appears with severe budget constraints and the goal of commercially affordable sophisticated phased arrays. Less than 3 years ago aiRadar embarked on a challenge. Design and build an affordable modular scaleable triple baseline interferometric multi-aperture Synthetic Aperture Radar (SAR) with multibaseline GMTI that is totally software configurable, and can be used to investigate "massive MIMO" of 2 Tx and 4 Rx, or any other configuration, as a subset of the aiRadar's 1536 Tx and Rx elements. (now that is Massive MIMO). Then design and build a new aiRadar Radar Programming Language (aiRPL) that can be compiled and executed on an aiRadar Radar Processor Unit (aiRPU) with femptosecond jitter. The put the whole thing in a package no larger than a 27" monitor, with a mass of less than 10kg. Add multiple GNSS positioning with Real Time Kinematics, multiple attitude sensors, and up to 60 Gb/s serial interfaces to the aiRPU, to the 8TB of on-board storage and to the multi-aperture raw I/Q data for a GPU based Machine Learning and Control system, and you have a Cognitive Adaptive AI Enabled Radar that is truly affordable and very, very capable. The modular design allows scaling to an even more affordable 384 Tx and Rx element Phased Array with 15Gb/s Cognitive Adaptive Radar Interface for your proprietary ML algorithms that are totally hidden from aiRadar Inc., with 2TB of on radar storage, and a multibaseline interferometric phased array that can be software configured as a very compact multi-aperture SAR or a high resolution RAR, scanning 90 degree sectors electronically in azimuth with 30 degrees of vertical interferometry. Experiment to determine your real requirements and cost/requirement ratio, and then use the IP cores and hardware and firmware you experimented with to make your dreams come true.
