Real‐Time and Rapid Dynamic Missile Identification Utilizing a TiOx Memristor Array
Advanced Intelligent Systems, EarlyView.Real‐time missile target identification is demonstrated using an artificial intelligence model based on step‐weighted long–short‐term memory networks and a TiOx memristor array. The approach classifies five projectile types with enhanced early‐stage prediction through data augmentation and custom training strategies. Achieving 94.4% accuracy, the model

Wind measurements by parachute [PDF]
Tests used the 8 cm Lotta grenade as well as 12 cm M/70 and 10.5 m/62 grenades, released at altitudes between 2000 and 6400 meters. The parachutes were tracked by AP and RFK.

Advanced Intelligent Systems, EarlyView.This paper presents a degeneracy‐aware light detection and ranging (LiDAR)‐inertial framework that enhances LiDAR simultaneous localization and mapping performance in challenging environments. The proposed system integrates a dual‐layer robust odometry frontend with a Scan‐Context‐based loop‐closure detection backend.

Multi-Radar Bias Estimation Without a Priori Association
IEEE Access, 2018 A solution for multi-radar bias estimation without a priori association is provided for a decentralized multi-radar tracking system. We describe the systematic bias of radar with random finite sets by a pseudo-measurement of bias, which is derived at the
