In order to make full use of measurement information provided by sensors on the aerial carriers and efficiently make maneuvering target tracking under complicated conditions, this paper studies tracking methods of joint maneuvering target by airborne radar and Electronic Support Measure (ESM). Based on Interacted Multiple Model-Blue Linear Unbiased Estimation (IMM-BLUE) algorithm, this paper we...

−57− This paper explores the use of Ultra-Wideband (UWB) radar for tracking multiple moving humans. Because the ability to track human movement is useful for the wide range of security and safety applications, a number of technologies have been pursued for human tracking. Computer vision has limited performance in poor visibility conditions, while the performance of infrared imagers can be temp...

Opportunistic array radar is a new radar system that can improve the modern radar performance effectively. In order to improve its radio frequency stealth ability, a novel coordination method of opportunistic array radars in the network for target tracking in clutter is presented. First, the database of radar cross section for targets is built, then the signal-to-noise ratio for netted radars i...

A linear array radar can be operated as a multiple-input multiple-output (MIMO) radar or a directed beam radar. A MIMO radar transmits orthogonal waveforms on each array element, which can achieve virtual aperture extension. Compared to a directed beam radar, MIMO radar requires longer integration times to maintain the same energy on target. This results in narrower Doppler bins but increased r...

An adaptive-update-rate target-tracking algorithm is indeed a developed version of constant-update-rate tracking algorithms. The update rate is closely related with the level of target maneuvering and the required quality of tracking performance— the shorter the time intervals between two successive updates, the better the radar resources are made use of. Considering the needs of the phased-arr...

Many countries including India use the Russian made SAM-3 (Pechora) surface-to-air missile (SAM) weapon systems to protect their strategic and tactical infrastructure. The mathematical computations done in this paper, conclusively proves that SA-125 low-blow tracking radar of Pechora is vulnerable to jamming. A project was undertaken to overcome the jamming vulnerability of Pechora aiming to de...

Development of the Advanced Multi-Function Array Radar (AMFAR) by APL in the late 1960's represented a new dimension in radar system technology. AMFAR demonstrated the feasibility of automatic detection and tracking with resistance to environmental clutter through computer control. The development of automatic detection and tracking capability in AMFAR eliminated the inherent delays, errors, an...

A variety of UGV (Unmanned Ground Vehicle) applications pose the challenge that UGVs need to handle human detection and tracking in complex environments that include dusty, smoky and foggy conditions. These environments make a vision-based human tracking-by-detection system ineffective. To cope with this challenge, we build a radar-vision fusion system, utilizing a 77GHz 2D Delphi ESR (Electron...
