  This work characterises the effect of mutual interference in a planar network
of pulsed-radar devices. Using stochastic geometry tools and a strongest
interferer approximation, we derive simple closed-form expressions that
pinpoint the role played by key system parameters on radar detection range and
false alarm rate in the interference-limited region. The fundamental tradeoffs
of the system between radar performance, network density and antenna
directivity are captured for different path-loss exponents in the no-fading and
Rayleigh-fading cases. The discussion highlights practical design hints for
tuning the radar parameters. The accuracy of the model is verified through
network simulations, and the role of random noise on detection in sparse, non
interference-limited networks is characterised.
