Summary:The process of radar signals recognition is mainly based on deinterleaving process of signal time parameters. Signal spectrum recently has became a very distinctive radar signal feature. Within this subject frequency modulation on pulse (FMOP) is a very good descriptor of signal. The most popular and obvious method is application of digitising technique and specialized software performing fast Fourier transform. Such an approach of signal spectrum evaluation is relatively easy when signal is not limited in time. The problem is when short pulsed radar signals are discussed. Facing with that problem the paper presents a wideband signals compression principle using surface acoustic (SAW) dispersive delay lines (DDL), to measure instantaneous spectrum of short pulsed radar signals. Compressive receiver concept has been introduced and its relation to time frequency analysis has been presented. Basic theory of problem is described and experimental results are presented.
