XPAR-2 Search Mode Initial Design
Abstract
In this report, the initial design of a search mode for the Experimental Phased-Array Radar 2 (XPAR-2) system developed at DSTO is addressed. A track-while-scan search method combined with a one-step detection algorithm is proposed for implementation. Effects of discrete and distributed land clutter on detection performance are analysed. Limitation of clutter attenuation due to oscillator phase noise is addressed. Three options for waveform and pulse repetition frequency (PRF) selections are considered. Option 1 consists of 8 PRFs which are designed for detection of targets between 2 NM to 20 NM. Option 2 consists of two separate PRF sets (each consists of 8 PRFs), which are designed such that one is optimised for close range targets between 2 NM to 7 NM, and one is optimised for targets between 7 NM to 20 NM. Option 3 is similar to option 1, but with twice the coherence processing interval. In all three options, the 3-of-8 binary detection rule is applied. Option 3 is selected for initial implementation. A track-while-scan search regime combined with a sequential alert-confirm detection algorithm is considered for future research study.
