In response to the increasingly prominent issues of electromagnetic spectrum usage safety for communication and radar equipment,as well as the difficulty in quantifying the risk assessment of electromagnetic spectrum parameter leakage,this paper employs numerical and analytical methods to model the electromagnetic characteristic parameters of emission features,reception sensitivity,and antenna radiation characteristics for both friendly and adversary frequency-dependent equipments.By integrating the complete communication link structure of electromagnetic spectrum parameter leakage,the analysis is conducted from the perspectives of equipment effectiveness and the impact on the radio wave environment.Utilizing the concept of grid division,a method for calculating the probability of electromagnetic spectrum parameter leakage is proposed,and the calculation method is verified through simulation.The leakage probabilities for a ground-based fixed radar L1 and a 1000-hop transmission station M1 within the ranges of 300~450 km and 350~450 km,respectively,are calculated.This achieves a quantified assessment of the risk of electromagnetic spectrum parameter leakage,solving the problem of difficult risk quantification in electromagnetic spectrum parameter leakage assessment.
