Effective Barrage Noise Jamming for Spotlight SAR Using Extended Kalman Filter-Based Kinematic Parameter Estimation

Autor: Haemin Lee, Ki-Wan Kim

Publikováno v: IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Vol 16, Pp 6579-6600 (2023)

A barrage noise jamming method for spotlight synthetic aperture radar (SAR) with kinematic parameter estimation using extended Kalman filter (EKF) is newly proposed. The main objective of the proposed method is real-time generation of the jamming sig

An Integrated Raw Data Simulator for Airborne Spotlight ECCM SAR

Autor: Haemin Lee, Ki-Wan Kim

Publikováno v: Remote Sensing, Vol 14, Iss 16, p 3897 (2022)

Airborne synthetic aperture radar (SAR) systems often encounter the threats of interceptors or electronic countermeasures (ECM) and suffer from motion measurement errors. In order to design and analyze SAR systems while considering such threats and e

Feature Preserving Autofocus Algorithm for Phase Error Correction of SAR Images

Autor: Haemin Lee, Chang-Sik Jung, Ki-Wan Kim

Publikováno v: Sensors, Vol 21, Iss 7, p 2370 (2021)

Autofocus is an essential technique for airborne synthetic aperture radar (SAR) imaging to correct phase errors mainly due to unexpected motion error. There are several well-known conventional autofocus methods such as phase gradient autofocus (PGA)
