Serious ground clutter is of significant influence for target detection in an airship‐borne passive bistatic radar (ABPBR) using frequency modulated broadcasting signals. The authors propose a data segment processing scheme to recover the direct signal from multi‐path clutter and suppress the multi‐path in the surveillance channel in an ABPBR. Super exponential (SE) equaliser and sample matrix inversion algorithm are exploited to recover the transmitted signal and suppress the serious multi‐path interference, respectively. It is shown that the proposed algorithms can accomplish the target detection task effectively by computer simulations.
