Radar Emitter Number Estimation Based on Principal Component Analysis

  • Received Date: 05 Nov 2007
  • To estimate the number of radar emitters in a complex electromagnetic condition,a novel information-theoretic criterion was formulated based on the characteristic of eigenvalues extracted from the principal component analysis of received pulse envelope vectors and arranged in a decreasing order.Computer simulation shows that compared with the existing information-theoretic criterion,the proposed criterion has a 29% improvement in average correct estimation rate and a 0.09 s improvement in average computational efficiency when SNR(signal-to-noise ratio) varies from 4 to 8 dB.
