## Abstract

Echo model and ambiguity function for a slowly fluctuating moving target were established by the distance r between the target and the reference point at which the target moving direction intersects the baseline, the angle α between the target moving direction and the baseline, the ratio n in which the baseline is divided by reference point and the baseline range L as arguments in any bistatic triangle plane. The signal delay at receiver was approximately calculated using Taylor series expansion which was derived by T. Tsao. Based on the model above mentioned, the ambiguity function is more of universal significance and simplified because of the randomicity of reference point target and hypothesized point target selected and no north-referenced coordinate system required.
