Abstract: The present invention relates to a radar system for tracking a target using radar. A method for tracking a target using radar according to an embodiment of the present invention comprises the steps of acquiring attribute information related to the movement of the target via the radar; calculating a distribution function of respective properties by using the acquired attribute information; comparing the function to be compared corresponding to each attribute with the distribution function calculated for each attribute and determining whether the target is a target to be tracked or not based on a result of the comparison; and tracking the target when the target is the target to be tracked.

Abstract: A method for compensating low elevation angle errors of a multibeam radar in a multipath environment is provided. Embodiments of the present invention include: a step of receiving at least one target signal by a multibeam radar; a step of calculating an elevation angle of the target from the received target signal using a mono pulse method; a step of using a result, which used the mono pulse method, as an elevation angle of the real target if the elevation angle of the target is out of a first reference range; a step of selectively compensating elevation angle errors of the target using a void matrix calculated from a received beam pattern using search radar near-field measurement if the elevation angle of the target is within the first reference range and exceeds a predetermined threshold value; and a step of compensating the elevation angel errors of the target using an elevation error compensation table which is formed by algebraically converting a ratio of the signal intensity between the received beam and received beam adjacent to the received beam if the elevation angle of the target is within the first reference range and satisfies a second reference range below the predetermined threshold value.

Abstract: PURPOSE: An active type phase array antenna and active type phase array radar including the same are provided to produce transmitting/receiving module form by forming an arrangement transform unit between a radiation element array unit and a connector array unit. CONSTITUTION: A radiation element array unit(110) arranges radiation elements to a first type. A connector array unit(120) arranges RF(Radio Frequency) connectors to a second type which is different type with the first type. The connector array unit includes one or more RF connectors for correction. An arrangement transform unit(130) interlinks the radiation elements of the radiation element array unit and the RF connectors of the connector array unit. The arrangement transform unit comprises a RF connector connecting point connected to the RF connector for correction.
