Abstract
In the article is considered the principle of the formation of the measuring channel for multifunction phased array radar in tracking mode using one of the short-range air defense radar system as an example. A new approach to the problem is offered, which is based on considering the change of noise levels both in the measuring channel and in the dynamic model of the target being tracked and is adaptive to its motion in space. The number of simultaneously monitored targets is calculated under the condition of application of the proposed principle of channel formation. The efficiency of the obtained solutions is confirmed. The conclusion is made about the expediency of application of this method in the existing air defense systems, the modernization of which is currently underway.
Highlights
A wide range of tasks performed by multifunction phased array radar (MPAR) [1,2,3,4,5] creates a need for the use of various sets of probing signals for the implementation of each of its operating modes [6]
Signal S2 of an aiming radar (AR) of the 9K330 air defense missile system is a train of 32 linearfrequency modulation (LFM) pulses with the duration of 9.1 μs, and signal S3 is a quasi-continuous sequence of 210 radio pulses with the duration of 0.92 μs
1) the time allocated for tracking the target is made up of measuring cycles of a fixed duration of 8704 μs, which are repeated with the frequency of 38.3 Hz; 2) the portion of the cycle duration is used to form the measuring channel itself and is not directly involved in the measurement process, in other words, it corresponds to the loss of time
Summary
A wide range of tasks performed by multifunction phased array radar (MPAR) [1,2,3,4,5] creates a need for the use of various sets of probing signals for the implementation of each of its operating modes [6]. An example of such an MPAR is an aiming radar (AR) of the 9K330 air defense missile system (ADMS), which can employ two radar signals for tracking one target [7]:. Purpose of the article is: the possibility assessment of increasing the capacity of the existing radar equipment through the application of a new approach to the formation of the measurement channel
