Paper Abstract

Low frequency ultrawideband (LF UWB) bistatic synthetic aperture radar (BSAR) is able to provide the high-resolution BSAR image and obtain more information of the scene. Here, an imaging experiment of the LF UWB BSAR using the fixed-receiver configuration is presented in the paper. In August 2015, based on the monostatic LF UWB SAR system, a LF UWB BSAR imaging experiment was carried out, and the then LF UWB BSAR raw data was collected. This BSAR system has a LF UWB SAR system as the moving transmitter and the other LF UWB radar system as a fixed-receiver. The aim was to investigate the imaging property of the LF UWB BSAR system. One pulse per second (1PPS) signal in combination with the global position system (GPS) disciplined 100MHz oscillator from the GPS receivers were used to implement the time and frequency synchronization in this BSAR system. LF UWB BSAR image was obtained using the fast factorized back projection (FFBP) algorithm integrated with the subaperture-based spectrum equilibrium method. The excellent results are shown to prove the validity of the imaging experiment of the LF UWB BSAR system.
