A echo simulation algorithm for natural scene

Fast target deception jamming method against spaceborne synthetic aperture radar based on equivalent bistatic scattered fields

“…The size of the real scene is 512 × 512 pixels. The raw echoes of the real scene are firstly generated [15]. In this experiment, only bistatic scattered fields from the target are calculated by utilising the SBR techniques so as to generate the jamming signals.…”

The influence of a SAR sensor trajectory deviation on the pip azimuth position in echo signals simulation based on prearranged samples

“…E CHO SIGNAL SIMULATORS are widely applicable for the development of synthetic aperture radars (SAR) [1][2][3]. Signals formed by simulators are fed to the input of radar or its elements, so the equipment operation is checked in laboratory environment.…”

“…In echo signals' simulation the earth surface is usually modeled by the sum of point scatterers [3,4]. Because of the SAR resolution is very high, the number of scatterers totals thousands or tens of thousands.…”

“…Because of the SAR resolution is very high, the number of scatterers totals thousands or tens of thousands. The simulated signal is formed as a superposition of partial signals reflected from scatterers [3]. The signal complex envelope is…”

“…Consequently present methods of echo signal simulation may be divided into two principal groups. In the first case, signal samples are directly calculated in real time [1], in the second one, they are prepared previously [3,4]. The first group drawback is noted above.…”
