• In this paper, we analyze the interstation direct wave interference (IDWI) under an asynchronous condition. We propose an array calibration method for the consistency of gain-phase for the first time and show the conditions and probability of the generation of IDWI and the characteristics of asynchronous IDWI. This method can implement calibration of direct wave without keeping radar stations in synchronous condition and perform outstanding precision and stability. The experimental data demonstrate that using array calibration for gain-phase errors based on asynchronous IDWI can get accurate and stable calibration values of gain-phase errors.
