ISAR Imaging of Maneuvering Targets Based on the Modified Discrete Polynomial-Phase Transform

Abstract: Inverse synthetic aperture radar (ISAR) imaging of a maneuvering target is a challenging task in the field of radar signal processing. The azimuth echo can be characterized as a multi-component polynomial phase signal (PPS) after the translational compensation, and the high quality ISAR images can be obtained by the parameters estimation of it combined with the Range-Instantaneous-Doppler (RID) technique. In this paper, a novel parameters estimation algorithm of the multi-component PPS with order three (cubic … Show more

“…The fundamental procedure of PSO is as shown in Figure 2. (6) where ′ c ( ) S f is the residual signal in the frequency domain and b f is the neighborhood range. The minimum neighborhood is = b 1/ f T ; the robustness can be increased by extending the neighborhood range properly.…”

“…To process mc-PPS effectively, two methods are popularly adopted. The first is polynomial phase transformation (PPT) [5], whether discrete polynomial phase transformation (DPT) [6], high-order ambiguity function (HAF) [7], cubic phase function (CPF) [8], and so forth, all of which can reduce the phase order based on phase differentiation (PD) and reduce the searching space to one dimension. These methods are influenced by the cross terms and their resolutions are limited by the PD process.…”

“…A detailed review of QML is presented in reference [13]. The second generally adopted method is polynomial phase transformation (PPT) [14], whether discrete polynomial phase transformation (DPT) [15], high-order ambiguity function (HAF) [16], or cubic phase function (CPF) [17], etc., all of which can reduce the phase order based on phase differentiation (PD) and reduce the searching space to one dimension. These methods are influenced by the cross terms and their resolutions are limited by the PD process.…”

“…ISAR imagery plays an important role especially in military applications such as target identification, recognition, and classification [1,2,3,4,5,6]. For ground-based radars, a perspective blind zone will exist when the height of the measured target is too low.…”
