Coherent integration and detection algorithm for hypersonic target based on modified pulse compression and Keystone transform

Abstract This letter considers the coherent integration and detection for hypersonic target in the first‐order approximate (FOA) echo model. The proposed algorithm first accomplishes the modified pulse compression utilising the designed reference signal, then conducts the Keystone transform (KT) bas...
