A high realized coherent integration gain often contributes to an improved performance. ... Nonlinear radar ...
Nonlinear radars can be utilized to detect electronic devices, which are difficult to detect with conventional radars due to their small radar cross sections (RCS). Since the receiver in a nonlinear radar is designed to only receive harmonic or intermodulated echoes from electronic devices, it is ab …Pulse compression is a method for improving the range resolution of pulse radar . This method is also known as intra-pulse modulation ( modulation on pulse, MOP ) because the transmitted pulse got a time-dependent modulation internally. The term CHIRP–Radar is often used in publications ( C ompressed, HI gh- R esolution P ulse, CHIRP).Apr 1, 2015 · The state of the art in nonlinear radar is conveyed by presenting high-level system architecture, explaining the rationale behind design decisions pertaining to that architecture, and listing the ... We propose nonlinear beamforming for phased array weather radars (PAWRs). Conventional beamforming is linear in the sense that a backscattered signal arriving from each elevation is reconstructed by a weighted sum of received signals, which can be seen as a linear transform for the received signals. For distributed targets such as raindrops, however, the number of scatterers is significantly ...
Dec 15, 2021 · This paper presents a new SIMO radar system based on a harmonic radar (HR) stepped frequency continuous wave (SFCW) architecture. Simple tags that can be electronically individually activated and deactivated via a DC control voltage were developed and combined to form an MO array field. This HR operates in the entire 2.45 GHz ISM band for transmitting the illumination signal and receives at ...
