Abstract—Low Frequency Ultrawideband Bistatic Synthetic Aperture Radar (LF UWB BSAR) can produce the higher resolution image and obtain the added information of scenes. In the paper, a vehicle experiment of the LF UWB BSAR is described and the result is proposed. This BSAR system has a LF UWB SAR system as the vehicle-based transmitter and the other LF UWB radar system as a ground-based receiver. In August 2015, the vehicle experiment was conducted in Changsha in China, and the LF UWB BSAR raw data was collected. The aim was to investigate the imaging property of the LF UWB BSAR system. 1-PPS signal in combination with the Global Position System (GPS) disciplined 100MHz oscillator from GPS receivers were used to implement the time/frequency synchronization of LF UWB BSAR systems. Bistatic image was obtained using the subaperture spectrum equilibrium method integrated with the Fast Factorized Back Projection (FFBP) algorithm. Excellent results prove the validity of the vehicle experiment of the LF UWB BSAR.
