Joint Estimation of Angle and Polarization for Bistatic MIMO Radar with Polarization Sensitive Array Using Dimension Reduction MUSIC

Abstract

In this paper, we propose a new blind direction-of-departure (DOD), direction-ofarrival (DOA) and polarization estimation algorithm for bistatic polarimetric multiple-input multiple-output radar using dimension reduction multiple signal classification. The proposed algorithm obtains the initial estimation of DOD via the signal subspace, then utilizes onedimension (1-D) local searching to estimate more accurate DOD according to the initial estimation of DOD, and finally joint estimates DOA and polarization by means of the receive polarization steering vector. The proposed algorithm, which convert multiple-dimension peak searching to 1-D local searching, can avoid the high computation cost. Simulation results show that the proposed algorithm has better angle and polarization parameter estimation performance than both estimation of signal parameters via rotational invariance technique algorithm and trilinear decomposition algorithm. Furthermore, the proposed algorithm can obtain automatically paired multi-dimensional parameter estimation.

Joint polarisation and frequency diversity for deceptive jamming suppression in MIMO radar

“…After obtaining the estimated angles, we estimate the ranges. According to (16), when , directly estimating the ranges is difficult using conventional algorithms, such as ESPRIT and multiple signal classification (MUSIC) [11, 12, 14]. Therefore, a paired polarisation scheme is proposed, which means that transmit polarisation vectors of two adjacent antennas in the transmit array are the same in each CPI, i.e.…”

“…In recent years, with the rapid development of multiple‐input multiple‐output (MIMO) radar theory, polarisation information processing and frequency diversity technology have been applied in MIMO radar systems. The polarimetric MIMO (P‐MIMO) [5–16] radar system (distributed and co‐located) and the MIMO radar system with a frequency diverse array as the transmit array (FDA‐MIMO) [17–20] have been proposed.…”

“…The problems of detecting different targets and backgrounds using the distributed P‐MIMO radar system are studied in [7–10]. The direction‐of‐departure, direction‐of‐arrival, and polarisation parameters estimation methods for the bistatic P‐MIMO radar system are explored in [11–14]. However, few studies have focused on the potential capacity of the P‐MIMO radar system to counter deceptive jamming.…”

Game Theory Design for Deceptive Jamming Suppression in Polarization MIMO Radar

“…The problems associated with detecting different targets and backgrounds using the distributed polarization MIMO radar system were studied in [6]- [9]. The directionof-departure (DOD), direction-of-arrival (DOA) and polarization parameter estimation methods for the co-located polarization MIMO radar system were explored in [10]- [13]. However, few studies have focused on the potential capacity of polarization MIMO radar systems to counter deceptive jamming.…”
