摘要

A relative delay measurement system for digital wideband array radar using linear frequency modulation (LFM) waveform is put forward. Based on stretch processing technique and applying digital decimation method, the proposed measurement system can work at low processing rates, thus effectively reducing the computation and lowering hardware complexity. Moreover, by means of reasonable parameter setting and unique design construction, relative delay values among multiple digital transmit/receive (T/R) modules can be measured at one single measurement process. Specific conclusions are testified by simulations.
