Areté, an employee-owned company, is an advanced science and engineering company that provides innovative solutions to the most challenging technical problems faced by the United States Defense and Intelligence agencies. Areté is derived from the Greek word "ἀρέτη", meaning the pursuit of excellence and the achievement of maximum performance.Areté was founded in 1976 by five scientists, tasked by the DoD to help solve the challenge of detecting weak signals in heavy clutter over very wide areas. The signatures involved in this work were so weak that any advancement in signal processing algorithms demanded a new approach and understanding of the underlying fundamentals affecting the sensors and signal phenomena in the environments of interest.This first-principles-of-physics approach has been a hallmark of Areté's development programs for the past 40 yearsAreté now works across the electromagnetic spectrum. We develop sensors and the associated signal processing algorithms necessary for the extraction and interpretation of data for systems operating under water, in the atmosphere, and in space.With our emphasis on enhanced signal processing and real-time executable software, Areté is able to improve the performance of existing sensor systems at fractions of the cost and time to operations of replacement systems. We work directly with customers and partners seeking maximum performance.Building on our expertise in detection theory we will continue to exploit the contextual, spatial, spectral, and temporal characteristics of data, incorporating them into our signal processing algorithms. These robust algorithms will continue to enable Areté to rapidly deliver innovative solutions to the ever evolving challenges of our customers.
