Abstract
Conventional radar altimeter systems such as Pulsed or Frequency modulated continuous wave (FM CW) have limitations on measurable range and security. In this paper, we propose a Direct sequence spread spectrum (DSSS) based radar altimeter that offers good resolution and low probability of intercept. We carried out MATLAB simulations of the system and verified the results with a scaled down prototype model. Various system performance measures including Bit error rate (BER) were computed and compared with the theoretical results.
