Detection of the air maneuvering target based on the reconstruction of time sampling in the airborne radar

An algorithm for detection of the air maneuvering target based on the reconstruction of time sampling is proposed. Space sampling is used to reconstruct time sampling, which is equivalent to increasing the number of time sampling in one array element. So the problem that the estimation precision is low when using the fractional Fourier transform (FRFT) directly is solved, which is caused by the limited pulses transmitted by the airborne radar in a Coherent Processing Interval (CPI). This algorithm improves the estimate precision significantly. Simulation results are provided to testify its validity.
