The Jindalee operational radar network: its architecture and surveillance capability

Abstract

The expansive surveillance capability of the Jindalee Over-the-horizon Operational Radar Network (JORN) stems in part from the ability to centralise control and co-ordination of remote sensors. The two radar sensors are located at Laverton, Westem Australia and at Longreach, Queensland, while the surveillance co-ordination centre is situated in Adelaide, South Australia.An extensive communications network will be developed to support the radars and their associated frequency management systems. The principle of operation, configuration and the key architecutral components of the Jindalee project are briefly outlined to provide the context of the Surveillance capability.

Optimal training sample partitioning for two-stage adaptive detectors

“…For antenna arrayed radar systems with many more sensors than the number of dominant interferers (M m), such as the Australian Jindalee high-frequency over-the-horizon radars with their M = 480 digital receivers [32], this saving in sample support is crucial. Moreover, the two-stage detection schemes considered here do not rely upon any CFAR properties of the detector, that in most practical applications are not invariant (due to the various mismatches).…”

HF skywave MIMO radar: The HILOW experimental program

“…Modern implementations of this class of radar have the requisite transmit subsystem hardware to support non-causal transmit beamforming [29], [30]. Typical skywave OTHR have separate transmit and receive apertures located some distance d tr (typ.…”

“…The High Frequency (HF) OTHR used in the experiment was the JORN Laverton radar located in West Australia. See [30] for a description of JORN. See [23] and [24] for a detailed signal model and further description of the experiment, together with related discussions and results.…”

MIMO radar limitations in clutter

“…In a series of papers [1]- [6] we have reported our investigations into the use of multiple-input multiple-output (MIMO) radar techniques [7], [8] for over-the-horizon radar (OTHR) [9]- [11]. Topics covered include; perspectives on how MIMO may be applied in OTHR, the impact of MIMO on transmitter sub-systems, using MIMO to determine the directionof-departure of a radar signal from a transmitter array, and, a demonstration of adaptive spatial clutter rejection using adaptation-on-transmit implemented using MIMO techniques.…”
