“…Most of the previous research in netted radar system only considered the simplest case of netted radar sensitivity. The radar parameters for every transmitter and receiver are the same and an isotropic radiator, giving a constant RCS in all directions except for the distance from transmitters and receivers to target [15][16]. But this is not an accurate consideration to calculate the SNR of stealthy target because the RCS value varies with elevation angle and azimuth angles, with the ground plane effect involved, the value of outdoor range RCS will be different from the actual target RCS.…”

A proposed detection technique for stealthy target model F-117A based on balloon-borne netted radar system is applied. One of the potential problems of the proposed scheme is the ground plane effect caused by the high altitude platform. In this paper, we present a proposed study of the ground plane effect on the stealthy detection based on a new hybrid of the physical optics (PO) and time difference of arrival (TDOA) methods. Through simulation, the effect results of all parameters characterizing the clutter on balloon fall point distribution are obtained. To achieve high location accuracy of stealthy model, we proposed a scheme of detecting stealthy model in ground plane effect by using accurate radar cross section (RCS) measurement to compute the stealthy target position based on PO formulation. The netted radar sensitivity of proposed scheme has been improved due to increasing PO-scattered field of stealthy model with higher aspect angles of balloon-borne comparing to the conventional ground-based netted system, which has limited observability and poor detection due to low signalto-noise ratio (SNR). Simulations demonstrate that proposed scheme gives much higher location accuracy and reduces location errors comparing to the conventional system.

However, in practice, the scattering of electromagnetic energy from a stealth target is a rather complicated phenomenon, which depends on a number of factors (stealth target geometry, size, shape, orientation (aspect) and altitude with respect to radar antenna etc.).…”

This study deals with an improvement of radar cross section (RCS) of stealth target model such as F-117A with a higher aspect vision, and proposes a new detection technique based on stratospheric balloon-borne netted radar system. Normally, it is very difficult to statistically model a stealth target by conventional analytically probability density function (pdf) expressions. Thus, a novel non-parametric detection technique using time difference of arrival (TDOA) and physical optics (PO) approximation method is proposed. Finally, Legendre orthogonal polynomials (LOP) using to reconstruct the pdf of stealth RCS predicted by PO. The potential problem of proposed scheme is instability of the platform caused by sudden gusts of winds. The balloon flight control is studied in detail by considering external force of wind that is typical random process with Dryden turbulence spectrum. The proposed geometrical structure of radar system is composed of one transmitter and multiple receivers. To achieve high accuracy of locating a stealth target, the proposed scheme uses accuracy RCS measurement to compute Stealth target position. Simulations demonstrate that proposed scheme using one transmitter and multiple balloon-borne receivers give much higher location accuracy comparing to other geometrical systems because of increasing the PO -scattered field with higher aspect angles.

A novel detection for stealthy target model F-117A with a higher aspect vision is introduced by using Stratospheric Balloon-borne Bistatic radar system. The potential problem of proposed scheme is platform instability impacted on the balloon by external wind force. The flight control system is studied in detail under typical random process, which is defined by Dryden turbulence Spectrum. To accurately detect the stealthy target model, a real Radar Cross Section (RCS) based on physical optics (PO) formulation is applied. The detection of proposed scheme has been improved due to increasing PO-scattering field of stealthy model with higher aspect angle comparing to the conventional Ground-based system. Simulations demonstrate that proposed scheme gives much higher location accuracy and reduces location errors.
