Aiming at the relatively complicated methods of zero-line detection of artillery, and the limiting of high requirements for target range measurement or the field of calibrating artillery of combat troops, this paper presents the method that laser alignment is applied to complete zero-line detection of artillery. This paper introduces the basic principles and methods of the method, and conduct theoretical analysis, modeling and calculation and determination of related parameters based on the optical principles of laser. This method can be used to complete zero-line detection of artillery in small venue, and provide convenient conditions for the detection for aiming line of artillery, the method is especially suitable for limiting of the field of calibrating artillery of combat troops, and calibrating artillery before shooting in a relatively harsh climatic conditions.

AbstractDifferent from traditional multiple-input and multiple-output (MIMO) radar, the frequency diverse array MIMO (FDA-MIMO) radar generates beampattern that is dependent on both range and angle, making it applicable for joint range–angle estimation of targets. In this paper, we propose a novel time reversal based FDA-MIMO (TR-FDA-MIMO) approach for target detection. Based on the time reversal theory, the TR-FDA-MIMO signal model is established, the TR transmitting–receiving and signal processing procedure are analyzed, and the resulting range–angle spectra for targets imaging are acquired by utilizing the multiple signal classification algorithm. Numerical simulations are carried out for both single and multiple targets cases. The imaging resolution and robustness to the noise of the proposed approach are investigated and results are compared with conventional FDA-MIMO radar. It turned out that by cooperating with TR, the performance of FDA-MIMO radar for target range–angle estimation is effectively enhanced, consequently improving its applicability in practical target-detecting cases.
