“…Underwater target passive localization technology is of great importance in the field of sonar detection. At present, there are three main passive positioning techniques: target motion analysis [1]- [5] (TMA), matched field processing [6]- [11] (MFP) and ternary array passive positioning [12], [13], among which the ternary array method is commonly used because it does not consider environmental factors such as the vertical distribution of channel sound speed and multipath effect, and the key to positioning is the time delay estimation of the received signals of the three arrays. The generalized correlation delay estimation method was first proposed in 1976 [14], and the current delay estimation algorithms are generally classified into mutual correlation method [15], [16], phase spectrum method and adaptive filtering method.…”

The ternary array passive positioning technique performs the estimation of target distance and bearing by measuring the time delay difference between array elements. The estimates are limited by the geometric model and time delay measurement errors, and the positioning accuracy and reliability are poor. In this paper, we propose an orientation matching-based motion target localization model. By introducing the target motion model, and establish a matching objective function for the time delay difference obtained by calculating the predefined target motion trajectory and the actual received data of the ternary array separately. The matching objective function is optimally solved by using Burg algorithm in the AR spectrum estimation method, and a highly accurate and reliable target parameter estimation can be obtained in a short time. The results of computer simulation experiments verify the effectiveness of the method.

“…In [11], a squint biased proportional navigation guidance (BPNG) was proposed, which provides visibility of an intractable target and some observability improvement. PNG, in conjunction with the feedback of the relative range multiplied by the LOS angle, was developed for generating oscillatory missile motion in a planar [12] and a three-dimensional [13] homing engagement. A modified version of PNG for passive guidance applications was suggested in [14].…”

“…Under the proposed guidance law, the LOS angle approaches a certain value called the reference LOS angle (a design parameter) with oscillatory motion. Previous studies [12][13][30][31][32][33] indicated that oscillatory missile motion might be an effective means for improving target observability. The behavior of the proposed guidance law is similar to that seen in works in [12].…”

This paper proposes a biased proportional navigation guidance (BPNG) law providing enhanced target observability for passive homing missile systems against a nonmaneuvering target. After examining the line-of-sight (LOS) rate equation, which is an important parameter of target observability and which reveals that the LOS rate is proportional to the rate of cross-range deviation, a bias term of BPNG is formulated using the rate of cross-range deviation to generate an additional LOS rate. The closed-form trajectory solution of the proposed guidance law is derived, and its capturability and characteristics are then investigated. Using numerical simulations, the performance of the proposed guidance law is determined in conjunction with a target state estimator.
