Transform sensing of phased array radar

Abstract

A completely new scheme called transform sensing is proposed for the phased array radar. The new scheme forms certain beam patterns, which directly perform desired transform, such as discrete cosine transform (DCT) or discrete wavelet transform (DWT), to the space. The received signals will be the coefficients of transform instead of raw data reflected from the target. By doing so, signal processing is performed in an online fashion to render attractive advantages which we never experienced before.
