This study deals with the problem of adaptively detecting range‐spread targets in Gaussian environment, by assuming a persymmetric structure covariance matrix. A detector based on two‐step generalised likelihood ratio test design scheme is devised to reduce secondary data requirement, which ensures constant false alarm rate property. Moreover, general closed‐form expressions probabilities and detection for proposed are derived, both cases deterministic fluctuating scatter models. Furthermore, compact versions forenamed presented special case when joint space‐time dimension received signal odd. Finally, numerical results these derived statistical confirmed those Monte Carlo trials.
