N2 - Frequency agile radar (FAR) exhibits robustness against active deceptive jamming and effective clutter suppression. However, effective coherent integration of target echoes under random agile waveform transmission remains challenging. This article proposes a compressed sensing (CS)-based improved sparsity adaptive matching pursuit (ISAMP) method within a joint transmit-receive processing framework. First, a Whale optimization algorithm (WOA)-based optimized random interpulse frequency and pulse repetition time joint agile (RI-FPrtJA) signal model is systematically derived. Then, the ISAMP algorithm achieves coherent integration of RI-FPrtJA echoes through two key enhancements: an adaptive regularization-based mesh mismatch correction strategy enhances mesh mismatch correction capability, and an adaptive searching extension condition reduces computational cost during sparse reconstruction. Qualitative and quantitative simulations demonstrate that ISAMP outperforms existing CS-based algorithms (e.g., orthogonal match pursuit and sparsity adaptive matching pursue) in sparse reconstruction under complex scenarios. Furthermore, the WOA-optimized RI-FPrtJA waveform can significantly improve the sparse reconstruction of agile echoes.
