“…The GCU microcontroller reads data from the GPS Receiver (3.6) of the Ground Shooting Unit (3) and receives data from another GPS Receiver (5.4) and Altimeter (5.5) of the Onboard Target Unit (5) with the help of RF transceivers (3.5, 5.3). These data refine the simulation [19], [20]. These data also refine the missile flight simulation.…”

In this article, the engineering concept of the laser-guided very short range air defence system field simulator, its structure, and practical use are presented. The possibilities and advantages of the practical use of the equipment developed in tactical exercises and individual training of air defence specialists are shown. The field simulator equipment without invasion and compromising functionality into the combat air defence system has been connected and installed. The simulator performs all required shooting procedures without using combat missiles, target detection, shot execution, and maintaining the target in the sighting lens until its destruction. The field simulator reduces training process expenses and increases its efficiency. In the article, the ground control and onboard control units are presented. The units consist of target detection and its positioning, coordinate defining and data transmission (global positioning system (GPS), personal computer (PC), radio frequency (RF) transceiver), pyrotechnic charge for missile launch simulation, and target destruction devices (e.g., smoke generator), whose operating principles, functional capabilities, and work reliability are ensured on the basis of conducted research. The field simulator, which was created based on synthesising the simulator systems studied, has proven itself in practise.

Forward‐looking radar imaging is a top priority due to a variety of applications. An airborne forward‐looking radar imaging approach via a modified propagator method (MPM) based on the planar phased array is proposed. It can obtain a better focusing effect without range migration correction. Through the MPM algorithm, the azimuth resolution can be enhanced greatly. Compared with the conventional synthetic aperture radar imaging algorithm, the left‐right ambiguity process can be avoided by generating two‐dimensional spatial spectra. Furthermore, the imaging results of different numbers of elements are given to provide an assessment of the imaging performance. Additionally, the authors proposed to apply the scanning planar phased array configuration to airborne forward‐looking two‐dimensional imaging for the first time. The validity of the method is proven by experiments. The image is more focused. Furthermore, the results of the experiments verify that the proposed method is fit for high‐speed situation and aircraft height variation condition.
