Real‐time missile identification using artificial intelligence (AI) is becoming a crucial element in modern warfare that can significantly affect the national air defense. In this study, a real‐time missile target identification (MTI) AI model is developed using step‐weighted long–short‐term memory networks based on a bit quantization scheme of the fabricated 1 kbit TiO x memristor array to classify five missile types: nonthreat (Non), field gun (FG), mortar (Mt), rocket (Rk), and rocket‐assisted projectile (RAP). To enhance accuracy and address dataset imbalance during training, data augmentation techniques are employed, including random trajectory rotation and Gaussian noise into the radar cross‐section, as well as introducing a custom loss function and dynamic learning rate (LR) to enhance early‐stage prediction and accelerate learning. Employing these strategies, the proposed MTI AI model achieves a 94.4% accuracy at 3.2 s in identifying Non class, while average accuracy for five classes is 94.4% at 12.8 s. The model exhibits ≈43.6% greater accuracy at 3.2 s than that of the conventional model, and the estimated false‐negative rate can be kept less than 2.5%. This MTI AI model can reduce the uncertainty of premature alerts for unidentified targets and exhibit superior detection capabilities for identifying and targeting missiles.
