A transponder landing system (TLS) is an all-weather, precision landing system that uses existing airborne transponder and instrument landing system (ILS) equipment to create a precision approach at a location where an ILS would normally not be available.

The TLS EAB is an extended-range, terrestrial sensing, collection, and electronic attack system providing integrated SIGINT, EW and cyber capabilities for situational awareness, situational understanding, Intelligence & Warning, command post survivability, critical asset protection operations, and supports the delivery of lethal and non-lethal ...

This paper compares two methods for adaptive signal processing in modem radar systems. We recall the working principles of the least squares (LS) and total least squares (TLS) algorithms. These processing methods are applied to three study cases in adaptive phased-array radar.

2020年8月17日 · That means TLS will have three very different options once it detects an transmission: keep listening and try to decrypt it (SIGINT), try to connect to the enemy wireless network and hack into it...

One such system, Transponder Landing System (TLS) precisely tracks aircraft using the mode 3/A transponder response received by antenna arrays located near the runway. These antennas are part of a measurement subsystem that is used to precisely determine the aircraft 3-dimensional position using TOA, DTOA and AOA measurement techniques.

Based on transponder multilateration, the tls is a performance-based system that complies with icao standards and recommended practices (sarps) for ils, secondary surveillance and precision approach radar (par). The tls tracks aircraft using their Mode 3/A and Mode S transponders to provide practically any airport a precision ils approach.

2024年8月1日 · This section describes our design and development of the multi-modal corner reflector (mmCR), the newly developed algorithms for locating the CR within the TLS point clouds and the radar images, and the accompanying algorithmic pipeline for georeferencing of TRI images with the TLS point clouds.

2004年2月17日 · 对航路 ATC 雷达分离的安全目标的审查表明，现有的目标安全水平 (TLS) 过于谨慎。 如果始终遵循风险预算原则，则“雷达 TLS”为 1·0×10 −9 每个飞行小时的致命飞机事故是适当的。 该比率与联合航空当局 (JAA) 关于导致灾难性事故的系统故障情况的指导一致。 比较使用已发布数据的动态和静态计算。 新方法显示了传统静态计算存在的问题，以及如何改进估计。 进一步的改进引入了控制器决策过程的简单稳健模型。 重点不是描述管制员通常会做什么，而是 …

The Transponder Landing System (TLS) is a precision approach landing system designed for use at airports where rough terrain or real estate constraints make Instrument Landing System (ILS) installation cost-prohibitive. All aircraft that are equipped to fly an ILS and are equipped with a transponder can also use TLS.
