Abstract

The invention provides a terminal for detecting and diagnosing atmospheric duct in real time. The independent terminal is connected onto a radar on active duty and has the capability for detecting and diagnosing the atmospheric duct on the premise that the work and the performance of a shore based radar or a ship-based connected radar are not influenced. The terminal comprises a work station (or a server) based on a compact peripheral component Interconnect (CPCI) bus, an interface module, a medium-frequency sampling digital receiver, a high-speed digital signal processor and an integrator formed by related software. The terminal acquires echoes and data by utilizing the connected radar, performs isolation and amplification through the interface module, then sends an original signal to the medium-frequency sampling digital receiver and the high-speed digital signal processor to be processed and converted so as to obtain sea clutter data, measures and calculates sea clutter power, performs atmospheric duct parameter inversion through atmospheric duct detecting and diagnosing software, and finally displays atmospheric duct parameters on a displayer of a control console. The terminal fully utilizes existing functions of the connected radar, does not influences normal usage, and is low in modification cost, convenient to install, high in reliability and suitable for radars with X wave bands, C wave bands and S wave bands.

Description

technical field [0001] The invention relates to the field of radar detection, in particular to an atmospheric waveguide real-time detection and diagnosis method and terminal configured on a shore-based or ship-borne high-performance radar to enable it to have atmospheric waveguide detection and diagnosis capabilities. Background technique [0002] The research on the operational application of battlefield environmental effects has always been valued by major military powers. In recent decades, the use of battlefield environmental effects has become a force multiplier. The complex marine and atmospheric environment has a significant impact on radar detection capabilities. The use of atmospheric waveguides over the ocean can significantly improve the actual detection efficiency of radars, and achieve beyond-horizon detection, warning, and tracking of long-range targets. The use of atmospheric waveguide detection can obtain significant combat benefits. Based on the real battle...
