A novel radar is proposed and verified based on a two-element time-modulated array. The distance of the object is estimated from the time delay between the source signal and the return one, while the direction is calculated by analyzing the spectrum

A novel direction finding method based on spatial spectrum estimation is proposed and verified with time modulated linear array (TMLA). Because of time modulation, harmonic components are generated in each element. Then, they are added together by a

The on-board calibration of aperture synthesis radiometers (ASRs) with large arrays by the standard method of noise injection would seriously increase hardware requirements and system complexity. To avoid the use of noise injection, an external phase

Traditionally, the system errors of synthetic aperture interferometric radiometers (SAIRs) are analyzed and classified by the causes they are generated, which is easy for understanding but complicated for calibration. This paper presents a new error
