Abstract: Modern radar systems commonly utilize multiple-input multiple-output (MIMO) architectures, which often result in non-rectangular virtual antenna arrays. For these non-rectangular ...

WASHINGTON — Array Labs, a Silicon Valley startup developing radar-based Earth observation satellites, announced Jan. 5 it raised $20 million in a Series A round as it pushes to bring lower-cost ...

Abstract: This letter considers two-dimensional direction of arrival (DOA) estimation of coherent signals exploiting a moving uniform rectangular array. The motion of the array induces phase ...
