P-band ultra-wideband bistatic synthetic aperture radar (UWB BSAR) has the well capability of foliage penetrating, high-resolution imaging and adding scattered information, which is potential detecting concealed target. However, UWB BSAR raw data huge amount, big spatial-variance, significant range azimuth coupling complicated motion error, increases difficulty efficient precise reconstruction. In this paper, we propose a reconstruction strategy for including errors, can solve above problems...
The bistatic space-based early warning radar (SBEWR) represents an innovative detection system, seamlessly integrating the advantages of and SBEWR, garnering increasing attention in field. However, extended range influence Earth's rotation pose signifi-cant challenges for SBEWR effectively suppressing ambiguous non-stationary clutter. This paper intro-duces a novel approach to address these by exploiting dependence both azimuth elevation spatial frequencies SBEWR. Initially, our method...
The ultrahigh frequency ultra-wideband synthetic aperture radar (UHF UWB SAR) has the well foliage penetrating and high-resolution imaging, which can be used to detect concealed area under in forests. This paper presents an airborne UHF SAR experiment imaging results. During winter, campaign been carried out Shanxi Province China, raw data was collected. In this experiment, system integrated onboard a CESSNA-172 airplane. antenna fixed on suspension arm of right wing airplane, while other...

The bistatic low frequency ultrawideband synthetic aperture radar (LF UWB SAR) has the well penetrating ability, high-resolution imaging as providing increased information. In this paper, an along-track LF SAR experiment and result are proposed. August 2015, was carried out, raw data collected. system, transmitter receiver both by a vehicle separated invariable distance. object to investigate property of system. Bistatic image obtained using subaperture spectrum-equilibrium method integrated...

Ultrahigh frequency ultrawideband (UHF UWB) synthetic aperture radar (SAR) system can penetrate the foliage, get high-resolution image, and add scattered information, which be used to detect concealed area under foliage. In fall, monostatic bistatic campaign with airborne UHF UWB SAR has been conducted. This experiment operates system, in conjunction a ground-based stationary receiver, simultaneously collect data. The fast factorized back projection (FFBP) algorithm applied process data, as...
This paper describes an azimuth-invariant bistatic experiment with P-band ultra-wideband synthetic aperture radar (UWB SAR) and presents imaging results. Bistatic UWB SAR has the perfect ability of foliage penetrating, high-resolution increased information. The transmitter receiver in this SAR, are both carried by a vehicle separated constant range. We use fast factorized back projection (FFBP) method subaperture spectrum-equilibrium to reconstruct image, which is used test property SAR....
