Cognitive radar parameter optimization in a congested spectrum environment

This paper presents experimental results with the Cognitive Detection, Identification and Ranging (CODIR) testbed set up in a congested spectrum and jammed environment. Band jamming is realized with a noise diode source, followed by power amplifiers and band pass filters. Special gapped linear frequency modulated (LFM) waveforms with minimal frequency content in the jammed band are designed and added to the standard LFM waveform list. Given a pre-defined performance goal in term of detection rate and track quality, the radar parameter optimization algorithm adapts bandwidth, pulse repetition frequency, integration time and pulse width such that time resources are minimized.
