Evaluation Method of Low Interception Performance of Spread Spectrum Radar Communication Integrated System

Abstract

The present invention discloses an assessment method of a low interception performance of a spread spectrum radar communication integration system which overcomes the problems that the assessment of the low interception performance in the prior art cannot reflect the quantitative relation between a radar communication integration emitter, a reconnaissance plane, work environmental parameters and acommunication function and the low interception performance, does not reflect the influence of the working modes of a transmitting antenna and the radar communication integration emitter on the low interception performance and causes and non-real assessment result. The method comprises the implementation steps of: (1) constructing a low interception performance assessment structure model; (2) calculating radar information capture probability of a radar reconnaissance plane; (3) calculating a communication capture distance; (4) determining a normalization communication capture distance; (5) setting an influence factor; (6) obtaining a low interception performance characterization amount; and (7) verifying a low interception performance. The assessment method considers the detection performance and the communication performance of the radar communication integration system and the parameters and working modes of the transmitting antenna to allow the assessment result to be more real and complete.

Problems solved by technology

However, the disadvantage of this method is that it only considers the impact of the waveform complexity of the transmitted signal on low intercept performance, and does not fully consider the influence of radar communication integrated receiver, radar reconnaissance aircraft, working environment and communication functions on low intercept performance. The impact of the low intercept performance is not comprehensive, and it is not suitable for the low intercept performance evaluation of the integrated radar communication system

However, the disadvantage of this method is that it does not consider the influence of the transmitter antenna parameters and working mode on the coverage area of ​​the main lobe of the radar transmit beam, and cannot comprehensively and accurately evaluate the low intercept performance of the integrated radar communication system.
