Special Approach for Estimation Ground Target Position in Passive Location
Ground target tracking is difficult and actual problem. Because of the high target density and maneuverability, high clutter, low visibility due to terrain masking, etc, ground target tracking presents unique challenges not present in tracking other types of targets. But many tracking approaches have been developed for air targets and they may poorly when used to track ground targets. This article includes results of the research work in estimation radar position in passive rangedifference location. Radio source is not moving and perform circular scan. Signal from it is received in three points. But beside true measurements of time difference of arrival (TDOA) there are false measurements originated by clutter. Usually clutter measurements are modeled as independed identically distributed. But processing real experimental data shows that in crosscountry it distribution may be multimodal. Therefore standard tracking algorithms are not efficient in this situation. Multimodal distribution is caused by re-reflected signal from underlying terrain. Some ground objects re-reflect signal and imitate additional (false) targets. We propose special approach to decide problem of position estimation in such high clutter environment and verify it on experimental data.
