WebThe RSR 936N is a 3D mechanically stabilised, continuous scanning surveillance radar, optimised for the simultaneous detection of both air and surface targets. The RSR 936N is a fully coherent, low cost, light-weight, Low Probability of Intercept (LPI) Frequency Modulated Continuous Wave (FMCW) radar. WebOct 25, 2024 · A coherent random-modulated continuous-wave (RMCW) LiDAR transmits a lightwave modulated by a pseudo-random binary sequence (PRBS). The lightwave backscattered from targets is received and used to reconstruct the PRBS. Then, the time-of-flight is extracted by correlating the reconstructed PRBS and the original …
