Abstract :
The problem of efficiently simulating thermal noise and dynamic tracking errors in spread spectrum ranging receivers is addressed. A Gauss-Markov state space model is derived which simultaneously satisfies the conflicting requirements of high fidelity and fast-time operation. Initial validation results are presented
