![]() ![]() An effective scheme that compensates for the delay with a low computation cost is introduced. The probable performance degradation due to the existence of sensors measurement delay (ignored in all similar studies) is illustrated. A modified iterated extended Kalman filter is suggested as the basis to handle the multi-rate fusion problem. The details of coping with three common kinds of measurement, attitude, and location biases are explored concentrating on the effects of attitude bias as the main error source from the practical viewpoint. The main novelty of the present work is addressing a new scheme to solve the registration problem in a distributed network along with estimating accurate target acceleration, simultaneously. ![]() On the other hand, providing satisfactory target acceleration estimation would enhance the performance of a ground-based air defense system encountering a maneuvering target. Registration is the most consequential topic to be dealt with in a multi-sensor tracking system. ![]() The effectiveness of proposed scheme in comparison with the well‐known augmented proportional navigation law, with the absence and presence of guidance filter, autopilot dynamics and target maneuvers is illustrated through benchmark scenarios. The importance of guidance filter is highlighted in the present work employing a cubature Kalman filter. The second is related to existence of guidance filter which is assumed to be ideal in existing literature. The required conditions to insure the global stability are derived regarding this inevitable constraint. The first is related to existence of pursuer's acceleration saturation which is ignored in all existing solutions. Two momentous practical limitations are considered. Then, a nonlinear control scheme constructed from feed‐forward terms along with a nested saturated feedback strategy is suggested. With the aid of formulating problem in pursuer's line of sight frame, the exact feed‐forward acceleration commands are derived for a general target motion in three‐dimensional engagement geometry. It's also lightweight and ruggedized, giving you radio communications in the harshest environments.In this paper, a novel scheme of command to line‐of‐sight guidance law regarding the outstanding practical limitations is proposed. Remote control access lets you use the radio from a distance.This also means that it can be shipped and stored without COMSEC handling requirements. No security clearance needed - the URC is a non-CCI radio, so you don't need any special security clearances to operate it.You can also customize the radio to work in manpack, rackmount, vehicular and intercom applications. Multi-band, multi-mode radio gives you the flexibility to operate in both the AM/FM bands and VHF/UHF spectrum.General Dynamics designed its URC-200 LOS product line to provide highly dependable service and to withstand the most demanding, harsh treatment and situations in the field. LOS refers to any “Line-of-Sight” (LOS) radio antenna communications system and covers the entire non-commercial, service and aviation bands of the AM/ FM, VHF/UHF spectrum, from 30 MHz to 420 Mz. This upgraded radio offers full compatibility with all currently fielded URC-200 accessories. This family of field-proven radios is backed by over two decades of production experience. The URC-200 (V2) Line of Sight Transceiver makes radio communications easier and more effective – without compromising privacy.
